Maybe i should have been more exact.
"Real" animations, like the steering animation of the driver in rF2, are not possible in rF1.
What you can do, is using the possible different texture frames (00,01,02,...) to get a kind of animation, like e.g. the backfire.
But because you have only 2 texture frames for the headlight, you can only "animate" on/off. Or, in your case, also covered/uncovered.
And yes, there is a Script to import rF1 meshes into 3DSMax, but the last Version that supports ISIs rF1 conversion/export tool, is 3DSMax2010.
Z-Modeler should be able to import/export rF1 gmt anyway and for Blender i don't know it, because i don't use Blender.
Can you post a Link to the Mod where you have seen the shifting animation?
