3DS should stay , caus for static objects it's perfects and allowmultiple textures / materials.

For FBX , Beyond Virtual engine already supports it.

the problem is that each FBX plugin for maya or 3DSMAX or nay other
has it's particularities , and for example you must
follow some things when exporting from 3DSMAX and another rules when using Maya.


But this format is good in my opinion.
Collada is not bad also.
