Transparent surfaces after FBX Import

if its about normals on your models facing the wrong way. In your model import settings under normals&tangents make sure that the normals are set to "calculate" instead of import.

If the surfaces are ment to be looked at from both sides you can search for a double sided shader or just duplicate the whole surface and flip its normals.

Also the materials might have been duplicated for some reason. Try changing increasing the material size number in your mesh renderer to 2 and put a blank material into the second slot.

Tell me if that helps.

I had the same problem and if i selected the transparent object, the selected "Standard Shader" for the shader and then selected the Render Mode to be "Opaque", it fixed it... but there has to be a better, automatic way... this is not practical with large numbers of these objects.

I have the same issue after importing object in .fbx format or directly .c4d format from Cinema 4D.

Anybody faced that issue?

i work with maya and i'm not familiar with 3ds max BUT i had this problem when i just exported my mesh to mudbox for texturing , you know what is the problem ????
The Problem is when you create your model you do some extrudes , right ? Now in maya there is a option called TWO SIDE LIGHTING and whenever you check that you see that some faces are reversed , and are black , i think that may be you should search for that in 3ds max and find it to see what faces of your mesh are reversed !!!
