Arma Reforger:Collision Layer

Layers Setup

• Buoyancy
• Camera - Special layer for camera collision
• Character - For collider capsule of characters
• CharacterAI - For collider capsule of AI characters
• CharCollide - Used for Character-only collisions (e.g. wheels, which are otherwise raytraced)
• CharNoCollide - Only for objects, which are NOT supposed to collide with character
• Cover - deprecated?
• Debris - Special layer for debris, we want it to collide with e.g. static, but not dynamic objects or character
• Default - Default layer, will collide with everything
• Dynamic - For dynamic objects like props are moveable in world
• FireGeometry - Used only for damage, projectile tracing, etc.
• Foliage - Layer used foliage on vegetation (mainly on trees)
• Interaction - Special layer for interaction (usually not really used, only for special cases when any other collision layer used for interaction wouldn't be enough)
• Ladder - For detection of ladders vs character (used for get in on ladder)
• Navmesh - Navmesh layer for soldiers
• NavmeshVehicle - Navmesh layer for vehicles
• Perception - For trace to collide with ViewGeometry layer
• Projectile - for bigger projectiles (bigger than bullet - e.g. RPG rocket)
• Ragdoll - Special layer for ragdoll, e.g. character shouldn't collide with dead soldiers, when they are in ragdoll
• Static - For static objects like buildings
• Terrain - Special layers just for terrain
• Vegetation - use for "soft" parts of vegetation - e.g. leaves
• Vehicle - Original layer for vehicles
• VehicleCast - used by wheels
• VehicleSimple - used to collision between vehicles and static assets, should be more "rough" and made from as little as possible colliders
• VehicleComplex - used for collision between vehicles and characters

• ViewGeometry - Used only for perception (AI)
• Water -

LayerPresets	List of active layers	Description	Examples of usage
Main	Default	Default LayerPreset	Not really used anywhere
Cover	Cover	To be removed?
Character	Character	Used on character colliders
CharacterAI	CharacterAI	Special layerpreset with layer just for AI (they don't collide with vehicles for now, etc.)
Projectile	Projectile	Used by projectiles (bullets, rockets), interacts with FireGeometry
Vehicle	Vehicle	Collides with static and dynamic objects like buildings, props, other vehicles, etc.	On vehicles
VehicleFire	Vehicle FireGeometry	Same as above + Fire Geometry layer	On vehicles parts which can used both for collision and fire geometry
VehicleFireView	Vehicle FireGeometry ViewGeometry	Same as above + View Geometry layer	On vehicles parts which can used for collision, Fire and View
ItemFireView	CharNoCollide FireGeometry ViewGeometry	Used on props, items where collision with player is not desired - e.g. really small objects like chocolate bar
Door	Static Navmesh	Used on doors
DoorFireView	Static FireGeometry ViewGeometry Navmesh	Used on doors,	Same as above
Weapon	CharNoCollide	Used on weapons
Terrain	Terrain Navmesh	Special preset for terrain mesh, is set in GenericTerrainEntity	On terrain meshes
Prop	Dynamic	Used on dynamic assets - props	Used on assets like e.g. bottle, ammo box, chair, etc.
PropView	Dynamic ViewGeometry	+ View Geometry layer
PropFireView	Dynamic FireGeometry ViewGeometry NavmeshVehicle	Used on props which has only one geometry (no separated Fire geometry)
Tree	Static NavmeshVehicle	Used on tree/bush trunks (hard parts)
TreeFireView	Static FireGeometry ViewGeometry NavmeshVehicle	Used on tree/bush trunks (hard parts) where one collider can be used for both collision with soldier and then as Fire Geometry
TreePart	Dynamic	Used on tree parts - branches, twigs, etc.
CharNoCollide	CharNoCollide	Not used?
FireGeo	FireGeometry	Collides only with projectiles	Used on Fire Geometry type of colliders
Building	Static Navmesh	Used on buildings as they use static colliders (+ special layer for detecting for Navmesh)
BuildingFire	Static FireGeometry Navmesh	+ Fire and View Geometry layer	Used on buildings
BuildingFireView	Static FireGeometry ViewGeometry Navmesh	+ View Geometry layer	Used on buildings
RockFireView	Static FireGeometry ViewGeometry Navmesh	Used on rocks
Debris	Debris	Used on small debris pieces which should not collide with dynamic assets
Interaction	Interaction	Not used?
Ladder	Static Ladder	Used on ladders, mainly for detecting ladder itself, so player can "snap" on it, but also used as collision
Bush	Foliage	Used on "soft" parts of bushes
Foliage	Foliage	Used on "soft" parts of trees - leaves, needles
Wheel	FireGeometry CharCollide	Used on vehicle wheels
Glass	Static	Used on glass, in case Fire Geometry would need to be separated from normal collisions
GlassFire	Static FireGeometry	Same as above + Fire Geometry layer
