What's a LOD?

LOD means Level of Detail, and is a method of defining, via different variations of a model, how high or low the viewable quality of the model should be, and how it should interact with the environment.


<Resolution>

Truck-ResLOD.jpg

Defines which model to use, depending on several in-game conditions (view-distance, number of objects, CPU utilization, etc.). Can be any value from 0.000 to 9999(what's the limit?).

Geometry

Truck-GeoLOD.gif

Defines where the model will collide with other objects.
Should be very simple, and has to fulfil the following criteria in order to work:


Fire Geometry

Defines where the model will collide with bullets & rockets. If this LOD is not present the Geometry LOD will be used instead.


Hit-points


Memory

Named Selections that are used to define lights, entry points, etc.


Paths


Roadway


LandContact

Where the object touches the ground. (Defined by single vertexes per contact point.)


ViewGeometry
