The 3ds Max FBX plug-in processes any type of image map in almost any standard material channel. Anything that you map in the Diffuse, Specular and other channels translate to FBX, as long as they are not procedural maps.

The FBX plug-in can transfer bitmap image and Composite Layer maps. However, the FBX plug-in ignores files created with procedural mapping systems like Dent or Smoke as it does not currently support these mapping types.
