Edit file in 3D Studio Max.(repost)

Got a simple task: see [login to view URL] The animation with the soldiers was done with 3D Studio Max. I have the source file. I need to edit the file to change the color of the front soldier. The new color should be FFCC00. So you will open the file, change the color of this one element, and render again. That is all. Output must be in original format plus .avi and .mp4.
