When I import fbx from 3d max it presents this message. Does anyone know what it is? And if it is a problem, how to solve it?

i would say that the normals on your model are not setup properly. aside from that you never assigned smoothing groups which isnt a big deal (1st error).

Ah … I Correct the settings and made smoothing groups, did not appear anymore the message. Thank you very much for helping me. ^^
