=== Preparing mesh ===
==== Model orientation ====
One of the most important thing to begin with is making sure that your '''model is properly orientated.''' Similar to  '''weapons,''' there is one important rule to keep in mind
{{Feature|informative|Everything must be oriented as pointing along/towards the Y+ axis in Blender and 3dsMax and along Z+ axis in Maya}}
That means, when you are '''importing A3 weapon you need to rotate it by 90 degrees to the left!'''
[[Image:armareforger-new-car-orientation.png|thumb|center|1200px|''Properly orientated model example'']]
{{Clear}}
==== Splitting mesh into parts ====
In principle, following elements of the vehicle should be split to separate models
* '''Vehicle accessories''' (i.e. vehicle roof) used for creation of variants of the same vehicle like i.e. cargo or fuel variant of the same truck.
* '''Destructible elements''' (windows, breakable elements of the vehicle, etc)
* '''Emissive lights'''
{{Feature|informative|In contrast to weapons, '''most of the vehicle parts''' are  '''not using snap points''' and instead, they have same origin as parent object.}}
In this example, windows  '''(1)'''  & emissive lights  '''(2)'''  were separated to their own FBX files.
[[Image:armareforger-new-car-parts.png|thumb|center|1200px|''Vehicle parts'']]
{{Clear}}
If those elements are already separated to unique objects, then it's possible to select them '''one by one''' and save them as FBX file with export limited to '''currently selected object.'''
[[Image:armareforger-new-car-parts-export.png]]
Generally, such simple objects doesn't require skeleton but in case of more complicated elements (like gun mount), it's possible to add them to mesh.
==== Naming of objects ====
When it comes to naming, there are few important rules to keep in mind.
# '''_LODx''' suffix is used to indicate '''Level of Details.''' You can have '''up to 8 LODs.'''
# '''UBX_, UCX_, USP_, UCS_, UCL_, UTM_''' prefixes are used to mark '''Colliders'''
# '''OCC_''' prefix is used for '''Geometry Occluders'''
# '''COM_'''  prefix is used to determine geometry '''center of mass'''
There are also some general guidelines regarding naming of the vehicle parts on  '''Vehicle Pipeline - Parts'''  page'''.''' It's strongly recommended to follow those rules since most of the '''base prefabs are using those names by default''' to reduce duplication & make easier data management. On that page, there are also general guidelines regarding naming objects which are not explicitly mentioned there.
Vehicle can also have various small sockets for destruction, crew positions management and contextual actions. Some of the rules regarding slots naming can be found in  '''slots section of Vehicle Pipeline'''  page.
==== Creating colliders ====
Colliders are special type of objects which are used to calculate various kinds of collisions - be it physic simulation or tracing of bullet penetration. There are few rules regarding those colliders and most of them listed here - [[Arma_Reforger:FBX_Import#Collider_usage|FBX Import - Collider usage]]. In case of models imported from Arma 3, there are usually some convex components already present which could be used a base for collision geometry. It's recommended though to make at least fire geometries from scratch.
In case imported convex components are useless (too complex collision geometry or not detailed enough fire geometry) and completely new geometries have to be created, below there are some tips & rules.
===== Collision geometry =====
This type of geometry should be kept as simple as possible and amount of colliders should be also kept low. Simple type of colliders like convex, cylinders or cubes should be used. Large single shapes should be used to avoid issues with collision imprecision.
[[Image:armareforger-new-car-collison-geo.gif]]
===== Fire geometry =====
Penetration geometries can be bit more detailed and, in contrast to Real Virtuality engine, they don't have be convex. Usage of trimesh geometry can greatly speed up creation of detailed fire geometry.
[[Image:armareforger-new-car-collison-firegeo.gif]]
Some additional informations can be also found on Vehicles - Colliders and Fire Geometry.
===== Layer presets =====
Layer presets are used by engine to determine how given collider should behave when it collides with other object.. Layer Presets can be either directly defined in modelling software by adding custom property to object or can be changed in Workbench after successful import of the mesh. If you are using Blender, there is small official tool - Enfusion Blender Tools - to assist you with assigning correct game materials & layer presets on colliders.
[[File:armareforger-fbx-layers-blender-1.png|frame|left|200px|Blender - manual input]]
'''For creating custom attributes in 3dsMax, use only the Parameter editor in Animation menu,'''  otherwise the properties in exported FBX can't be edited in Maya. So doing it with Object Properties/User defined is '''FORBIDDEN '''
More details about  '''Collision Layers, Layer Presets and Interaction Matrix''' can be found on linked page.
{{Clear}}
==== Setting skeleton & rigging mesh ====
When creating skinned objects, Enfusion Workbench expects that the whole object is skinned to some bone. Otherwise importer will try to "fix" it by skinning remaining faces to some root bone.
In Blender realms, this means that any object which Armature modifier, must be fully skinned to some existing bone through vertex groups.
If you have some animated collider please keep in mind that '''only trimesh colliders can be skinned'''. In all other cases you have to use '''100% weight'''.
In Blender it gets even bit more tricky and '''Object Relations''' (in '''''Object tab''''') have to be used.
[[Image:armareforger-new-weapon-relations.png|400px]]
=== FBX export settings ===
Most of the general rules can be found on this page  '''this page''' . In principle, when export from i.e. 3DS Max, you have to make sure that you are exporting in '''binary format in version 2014/2015.''' Furthermore, '''Triangulation''' & '''Preserve Edge Orientation should be turned off.'''
Blender wise, there are 3 most important things to keep in mind when exporting FBX
{| class="wikitable"
|
# '''Object Types''':
For animated object like weapon you need to have checked on at least:
'''Empty -''' which handles all snap points
'''Armature''' '''-''' exports skeleton of your weapon
'''Mesh -''' self explanatory
| rowspan="3" |  [[Image:armareforger-new-weapon-export-blender2.png|200px]]
|-
|'''2. Custom Properties''':
Without this option all custom properties like '''LayerPresets''' would be lost!
|-
| colspan="1" |'''3. Leaf bones''':
Leaf bones are completely unnecessary in Enfusion and it's better to have that option '''turned off'''
|}
== Importing Mesh ==
'''Overview'''
In this chapter following topics will be explained
* Importing new model
* Importing textures
=== Importing & registering new model ===
Once mesh was successfully prepared and all selections, sockets & snap points are in place, it's time to try our asset in game. Majority of the process is already pretty well described on FBX import - Import process in the Workbench page.
In principle, all you have to do is click with right mouse button on your FBX files and select from context menu '''Register and Import''' option and then click '''as Model''' to import selected mesh as a game model.
{{Feature|informative|If you are importing models, it's worth to check "'''The same for all FBX files'''" option}}
[[Image:armareforger-new-car-importing.gif]]
==== Checking colliders & materials ====
After initial import was done it's time to make sure that materials & colliders are using proper materials & colliders. By default, Enfusion will try to assign material based on the name of the assigned texture in mesh. If it fails to find such texture, new dummy material (see area marked in orange on screen below) will be created in '''data''' folder next to the FBX model.
There are 2 typical errors when it comes to collider configuration:
[[File:armareforger-new-weapon-collider-errors.png|thumb|left|800px|Colliders errors example]]
{{Feature|important|Make sure that you have "usage" property defined in collider object properties.
[[Image:armareforger-fbx-layers-blender-1.png|200px]]
More info about it can be found on [[Arma_Reforger:FBX_Import]]}}
{{Feature|important|Make sure that correct material is assigned to all colliders
[[Image:armareforger-new-weapon-colliders-material.png|200px]]
More info about it can be found on [[Arma_Reforger:FBX_Import]]}}
{{Clear}}
==== Skeleton & hierarchy ====
Since this model is animated, it's very important to check '''Export Skinning''' & '''Export Scene Hierarchy''' checkboxes. Without those two parameters selected, vehicle will be imported without skinning or any sockets!
=== Importing textures ===
In principle, you can use same procedures as the ones described in [[Arma_Reforger:Weapon_Modding#New_Materials||Weapon Modding - New Materials]] creation page. By default, Workbench will new materials based on the materials name from the FBX file.
== Adding basic car configuration ==
'''Overview'''
Following topics will be covered in this paragraph
* Creation of new car
* Configuration of actions
* Configuration of crew
* Basics of wheeled simulation
* How to change engine parameters
* Changing of driving characteristics
=== Creating new prefab ===
When creating new vehicle, it's recommended to use one of the core vehicle prefabs located in '''Prefabs\Vehicles\Core.''' This way, most of the crucial components will be already present in new car prefab with already some of the parameters filled in.
Since this asset is a car, '''Wheeled_Car_Base.et''' is going to be used as base. Easiest way to do so is using '''Resource Browser''' attached to  '''World Editor'''  ( '''it's not going to work in Resource Manager!)  -'''  after navigating to '''Prefabs\Vehicles\Core''', click on  '''Wheeled_Car_Base.et'''  with ''Right Mouse Button''    and select from context menu "'''Inherit Prefab in Addon'''" option. After selecting name of new prefab, the only thing left to do is moving prefab that prefab to more appropriate folder in addon.   
[[Image:armareforger-new-car-inherit-in-addon.png]]
{{Feature|informative|Both above described method & alternative one are described in detail on [[Arma_Reforger:Weapon_Modding#Method_1:_Create_Inherited_Prefab|Weapon Modding ]] page.}}
Other method involves duplicating some already existing prefab - this might be handy if you are creating something similar to already existing cars. For instance if you are making some car with 2 axis, you could use '''Duplicate in "addon name"''' function on '''UAZ469.et''' prefab and then start to adjust parameters of newly duplicated file.
New '''SampleCar_01_Base'''.'''et''' prefab should already have almost all necessary components for adding new car to the game. Among missing components there are things like:
* '''SlotManagerComponent''' - this component is used to attach new elements to the vehicle like '''destructible parts''' (''windows'') or completely '''new elements''' (''machine-gun mounts'')
* '''VehicleSoundComponent -''' handles sounds that vehicle emits
With that prefab already being present, it's possible to starting changing properties so new car is resembling newly imported mesh. To do so, '''MeshObject''' component has to be changed and '''SampleCar_01.xob''' need to be applied to '''Object''' field. As a result, '''SampleCar_01.xob''' mesh should be now visible in  '''World Editor'''  view port.

=== Creating actions ===
==== Actions Manager Component ====
Before even vehicle can be entered, it requires setting up actions so engine knows where to show certain options like get in dialog. Those actions are configured in '''ActionsManagerComponent.'''
In this component you can find '''Action Contexts,''' which serves as a library of actions (somewhat similar to memory LOD in RV engine but with additional layer of information attached to it) & '''Additional Actions.''' Usually contexts defined in this component are used by other components (''like''  '''''BaseCompartmentManagerComponent'')'''
Each context defined in '''Action Contexts''' has option to change '''Context Name,''' '''Position, Radius''' & set if action is '''Omnidirectional.''' Position of the context can be either tied to bone in hierarchy or manually entered via gizmo controls. It is also possible to combine those two methods.
'''Allow Cross Hierarchy''' option is used when vehicle consist of multiple prefabs (attached via i.e. '''SlotManagerComponent''') where it's desired to be able use actions from attached components.
==== Creating action contexts ====
If vehicle has already some bones or sockets which could be used as position for action context, then it's possible to use '''Create user action context(s) from bones''' option which is available in context menu of '''ActionsManagerComponent'''. This menu can be invoked by clicking with ''Right Mouse Button''      on '''ActionsManagerComponent''' in components list.
[[Image:armareforger-new-car-action-context.gif]]
It's also worth to mention that this context menu has few other options, which are quite useful for setting up & debugging of context actions. Below you can see in action '''transform gizmos''' (activated via  '''''Toggle context(s) transform gizmo visualization''''' ) and '''radius visualization''' (activated via  '''''Toggle context(s) radius visualization'''''  option).
[[Image:armareforger-new-car-action-context-prev.png|center]]
{{Clear}}
Position of '''Action Contexts''' can be also adjusted inside of the view port. To do so, click with ''Left Mouse Button'' on one of the Offset fields (X, Y or Z). After, transform gizmo should snap to existing offset and it should be possible to manipulate location of the action. It is also possible to use '''Pivot ID''' parameter which will snap action context to selected bone or pivot - this option is especially useful if it's desired that action follow the bone like on turrets.
[[Image:armareforger-new-car-action-context-tweak.gif]]
For this particularly vehicle, following '''Action Contexts''' were created:
{| class="wikitable"

|-
|door_l01
| rowspan="4" |Those action contexts will be used to determine position of '''get in''' action. Recommended to place at the middle of the door

|-
| colspan="1" |light_interior
| colspan="1" |Action context for '''toggling interior lighting'''
|}
==== Adding additional actions ====
Additional actions are type of actions which are not part of other components. Usually those actions are scripted and it's possible to add new ones. For purpose of this tutorial, 2 new actions will be added:
* '''SCR_EngineAction''' - adds action to toggle state of the engine. In this example '''starter_switch''' should be added to '''Parent Context List''' of that action
* '''SCR_FuelReceiverUserAction -''' adds action to refuel vehicle. In this example '''fuel_cap''' should be added to '''Parent Context List''' of that action
=== Compartments setup ===
Compartments are used to define who, where & how units can access seats in the vehicle. Most of the configuration is performed in '''BaseCompartmentManagerComponent,''' where compartment slots are defined itself, and in '''ActionsManagerComponent''', which provides information about actions properties & their position.
==== Overview of compartments ====
By default,  '''Wheeled_Car_Base.et''' prefab already contains '''PilotCompartment''' slot. This slot defines '''driver''' of the vehicle. Bunch of parameters should be already inherited from parent prefab (like UI infos containing strings for actions), yet some of the values still have to be filled in. Those parameters which need to be update include:
* '''Compartment Action, Get Out Action & Switch Seat Action''' – those define which action contexts are used for '''get in''', '''get out''' or '''switch seat''' action & how it’s presented in game UI. '''Compartment Action''' (''get in action'') is available when player is outside of the vehicle and wants to, as name suggests, get inside. '''Get Out Action''' is present when player is seating on that slot. Finally, '''Switch Seat Action''' is available only when player is seating on some other seat in the same compartment of that vehicle and is looking at the action contexts defined by this action.
* '''Passenger Position Info''' – stores information about position of the character inside of the vehicle. (''Similar to seat proxies in RV engine'')
* '''Door Info List -''' contains information about actual get in & get out position & behavior. Here it is for instance possible to define if engine should play animation tied to the vehicle or if character should be instantly teleported in & out.
Making adjustments to those classes listed above should be enough to get first driver seat working in game. Rest of the properties are described in detail on Vehicle Compartments page.
==== Configuring compartments ====
[[Image:armareforger-new-car-compartment-context.png|right|400px]]
Having knowledge about what '''PilotCompartment'''  '''is, it’s time to start setting it up. In'''  '''Compartment Action, Get Out Action & Switch Seat Action''' main thing to do is adding '''parent contexts''' to '''Parent Context List'''. Now it’s proper moment to use '''action contexts''' created in previous step. In this example, following contexts will be used:
#  '''Compartment Action -> door_l01'''
#  '''Get Out Action -> door_l01_int'''
#  '''Switch Seat Action -> driver_idle'''
In case slot action can be performed from multiple sides (i.e. middle car seat – this one should be accessible from both left & right side), it is possible to define multiple contexts.
Next step on the way to fully functional car is configuration of '''Door Info List.''' In this class, contexts provided in '''Compartment & Get out Actions''' are linked to respective doors, so engine know where character should get out or which door should be animated during get in action.
In this example there are no actual get in or get out animations and simple teleport is used. To activate such behavior, '''Get In Teleport''' & '''Get Out Teleport''' should be checked.
{{Clear}}
Next step will be changing get in location in '''Entry Position Info'''. In this class it is possible to either define offset & angles manually or use one of the existing sockets present in the model. In this example '''Pivot ID''' is used & changed to '''driver_getin''' socket.
[[Image:armareforger-new-car-compartment-pivot.png|armareforger-new-car-compartment-pivot.png]]
By default, '''Wheel_Car_Base''' prefab doesn’t have '''Exit Position Info''' class present, so it has to be created by clicking with ''Left Mouse Button''  on '''set class''' button. Once class is there, similar steps to '''Entry Position Info''' class can be applied – in this case it will be changing '''Pivot ID''' also to '''driver_getin''' socket.
Once those steps are completed, it should be possible to get in & out from the vehicle. In both cases character will get in & get out at '''driver_getin''' socket location.
==== Adding new compartments slots ====
New compartments slots can be created in two ways:
* By '''drag & dropping''' one of the existing '''Compartment Slots''' configs (basic one are located in ''Prefabs/Vehicles/Core/Configs'') – this way some of the common parameters will be already inherited from selected config. When doing multiple seats of same type specific to some asset (i.e. Ural-4320 rear cargo seats), it is also recommended to create new, inherited config (''conf inherits from CargoCompartment_Base.conf'' ) which is then applied to such prefab.
* By '''clicking on arrow icon''' on the right side of the '''Compartment Slots''' – this will create new class of your choice with only default values.
[[Image:armareforger-new-car-compartments-overview.png|frame|left]]
Both of the methods are described in detail on Vehicle Compartments page. In most cases, it is recommended to use config solution, since it makes easier maintenance of such prefabs.
In this example, 4 additional cargo seats will be added to the vehicle using  ''CargoCompartment_Base.conf'' as a base.
Vanilla content is using following naming convention for passenger seats:
* '''Passenger_''' - prefix indicating type of the seat
* '''_r_''' - indicates whether seat side - '''left''' ('''_l_'''), '''right''' ('''_r_''') or '''middle''' ('''_m_''')
* '''01''' - row indicator - counting from front of the vehicle.
To add new Cargo Compartment Slot, locate  '''CargoCompartment_Base.conf'''  in Resource Browser and then drag and drop it on '''Compartments Slots''' property.
{{Clear}}
After that, similar to '''Pilot Compartment,''' it is necessary to fill in:
* '''Parent Action Contexts''' for '''Compartment Action, Get Out Action & Switch Seat Action'''
* Select '''Pivot ID''' or '''adjust offset''' in '''Passenger Position Info'''
* Adjust data in '''Door Info List'''
'''Passenger_m02''' is sort of special case since it is desired to be able to '''access that seat from both left & right side'''. To do so, it is necessary to two contexts to '''Compartment Action Parent Contexts List''' & then, create two entries in '''Door Info List''' where both contexts matches with those newly created entries.
{{Clear}}
[[Image:armareforger-new-car-comparments.gif]]
=== Simulation setup ===
Simulation for vehicles like cars, trucks or wheeled APCs is stored in '''VehicleWheeledComponent.''' This component holds information about configuration of engine, gearbox, suspension or wheels. More details regarding all available parameters in this component can be found on Vehicles - Wheeled Simulation page.
==== Engine parameters ====
When setting up engine parameters, it is possible to use real life values. Usually it's not that hard to find information about power & torque of engine with RPM data attached to it. Below is table containing example source data which will be used to configure vehicle in Workbench
{| class="wikitable"
| colspan="1" |'''Engine'''
| colspan="1" |'''Power'''
| colspan="1" |'''Torque'''
|-
| colspan="1" |I4 16V
|86 kW at 5,800 rpm
|155 N⋅m at 4,400 rpm
|}
Using that data, it is possible to fill following data in '''Engine''' section of '''VehicleWheeledComponent'''
* '''Max Power - 85 kW'''
* '''Max Torque - 155 N*m'''
* '''Rpm Max Power - 5800 rpm'''
* '''Rpm Max Torque - 4400 rpm'''
Below is visualization of data <nowiki>https://www.desmos.com/calculator/j63rwoyvnh</nowiki>
[[Image:armareforger-new-engine-diagram.png]]
'''Inertia''' parameter controls engine moment of inertia. In layman's term, it affects '''how fast engine gains or lose rpm'''. High inertia results in slower gain of rpm's but it also means that less rpm will be lost during i.e. changing of gears or when releasing thrust. Table below can be used as sort of guidance but it is still recommended to experiment with that value and tweak it till reaches desired state 
[[Image:armareforger-new-engine-inertia.png]]
'''Steepness''' parameter controls how fast engine can reach max torque. This parameter can be used to i.e. reduce the acceleration of the vehicle or to fine tune torque/rpm graph. Effect of that parameter can be observed below
[[Image:armareforger-new-car-steppnes.gif]]
Rest of the RPM parameters, like '''Rpm Idle, Min Clutch, Redline & Max''', can be also directly copied from source data if its available. In this example, following data was used
* '''Rpm Idle - 850 rpm'''
* '''Rpm Min - 600 rpm'''
* '''Rpm Clutch - 1500 rpm'''
* '''Rpm Redline - 6500 rpm'''
* '''Rpm Max - 7000 rpm'''
Last but not least, there is '''Output''' parameter, which controls where power produced by the engine is transferred. In this example '''Clutch''' is used as a '''Output.'''
==== Gearbox & Clutch parameters ====
[[Image:armareforger-new-car-axle-setup.png]]
In '''Clutch''' section of the '''VehicleWheeledSimulation''' component there are two parameters available. Clutch '''Output''' should be kept to '''Gearbox''' & '''Max Clutch Torque''' - parameter controlling maximum torque that clutch can provide - should be tweaked. '''1.6 *'''  '''Max Torque''' can be a good starting point.
In '''Gearbox''' section gear that can be filled in. In this example, following data was used as source
{| class="wikitable"
!'''Final drive'''
|68 : 16 = 4.250
|-
!'''1st gear'''
|38 : 11 = 3.455
|-
!'''2nd gear'''
|35 : 18 = 1.944
|-
!'''3rd gear'''
|37 : 27 = 1.370
|-
!'''4th gear'''
|32 : 31 = 1.032
|-
!'''5th gear'''
|34 : 40 = 0.850
|-
!'''Reverse gear'''
|38 : 12 = 3.167
|}
'''Forward''' parameter contains array of '''forward gears'''. New gears can be simply added by clicking on plus sign + on the right side of the parameter. '''Reverse''' parameter is used for '''reverse gear.'''  '''Final drive''' is defined later in differential which is defined in one of the '''Axles.''' Depending on the configuration of the vehicle, it is possible to do various types of drive trains. In this example car is using simple '''forward wheels drive.''' 
==== Suspension parameters ====
One of the most important part of the vehicle configuration is setting '''Axles''' & their '''Suspension''' values. First, it is necessary to add as many '''Axles''' as vehicle has. This can be done by clicking on '''plus +''' sign on the right side of the '''Axles''' property.
[[Image:armareforger-new-car-suspension-setup.png]]
==== Wheels parameters ====
===== Wheel =====
===== Tyre =====
===== Wheel Positions =====
==== Aerodynamics ====
Aerodynamics affects maximum speed and acceleration of the vehicle. Furthermore, aerodynamics drag is especially noticeable at '''higher speeds''', since '''drag increases with square of speed'''.
'''Reference Area''' & '''Drag Coefficient''' values can be obtained by using values of similar vehicles, which have already those values measured.  '''Drag Area'''  (''Reference Area)'' &  '''Typical drag coefficients'''    ''(Drag Coefficient) sections'' of Auto mobile drag coefficient wiki page can be used as reference. This page contains data for quite wide array of vehicles and in most cases it is possible to pick data for something similar in size & shape.
In this example, '''Reference Area''' was set to '''0.62''' & '''Drag Coefficient''' to '''0.31'''.
==== Pacejka ====


==== Debugging ====
== Creation Steps ==
The debug menu is accessible by holding '''''Windows Key + Left Alt'''''  or  '''''Windows Key + Left Ctrl''''' and if you are on Windows 11, hold all three keys simultaneously. While holding the aforementioned keys you can navigate the open menu using the '''Up''' and '''Down''' arrow keys. To modify the current selected setting use the '''Left''' and '''Right''' arrow keys. To enter a submenu use the '''Right''' arrow key and to leave the submenu use the '''Backspace''' key.
