The primary use of this data is to display animated objects in the environment (cars, helis, fans etc.). "Physics" may also work but the implementation is buggy and incomplete, you may be able to add a object that can be pushed around but if you try to jump on it you fall.




Elements m41, m42, m43, m44 of both transform matrices are missing. m41, m42 and m43 are the projection transform coefficients and they are not needed so they are 0.0 and the m44 element is always 1.0 for a transform matrix. (column major transform matrices like in Open GL, for Direct 3D they need to be transposed)
Position, rotation and scale are used only when the object is not animated, otherwise the origin matrix is used instead.




The initial position transform is used the place the object in the environment. For object that have an animation attached to them this is also the starting position of the animation sequence. The initial x,y and z position value together with the initial rotation quaternion and the initial scale factor contain basically the same information as the initial transform matrix and combining them in a transform matrix should result in the initial transform matrix (less the differences due to floating point computation errors)
Objects are not automatically created when a level is loaded, they need to be created from script using the obj_create command. After that they can be controlled with other commands like obj_show, obj_hide, obj_kill, env_anim and env_setanim. In some cases the object geometry has been baked into the environment and needs to be hidden (by using "env_show objectScriptID 0") before playing an animation.
