I'm not a 3DS Max user myself, so I don't know if it is common to use DDS textures in there already. Sounds a bit like 3DS uses a different origin for the texture mapping than FS.
Do you load a MDL or X file into MCX?
also when exporting, my mdl export is showing this and exports at 0kb, how do i fix this?:
