I use wing3d to do my 3d modeling and I export as a wavefront file.Then I put it in Unity and the UV mapping is gone.I know it’s not deleted or anything, can somebody just tell me how to relocate it.
I know Cinema4D won’t export the UV of an object if you don’t have a material on it with a texture assigned. You might be experiencing something similar. Also, if Wings3D supports it, export to the FBX format which Unity handles more gracefully.
it didn’t work…thanks anyway.
What is wavefront file?
Can you import that file into other 3d tool and see if UV is there (i.e. is it really problem in Unity, not in the exporter)?
Another name for Wavefront is a obj file.It’s not only a Unity3d problem, it happens a lot with almost every 3d tool. I just want to know how to relocate the UV maps with Unity3d.
Can’t you use fbx, or some other better supported format?
Are you including the MTL file with the OBJ file?
Hmm…I do see the MTL file and I know that that’s the material but, how do I get it back?
It should be generated alongside the OBJ file when exported from Wings3D. But as Paulius said, try to use a better format like FBX if Wings3D supports it.
Yes and I still lose the UV mapping,what I’m I doing wrong? 
Well if wing3d doesn’t export UVs than it’s not a problem in Unity and I can’t really help you on that.
How do you know that UVs are gone? And what do you mean by “I just want to know how to relocate the UV maps with Unity3d.”? If UV mapping doesn’t exist in exported file, than Unity can’t “recover” it. I’m clearly missing some point
Unity doesn’t auto-connect textures to objects (not for me anyway), so if you haven’t set your object’s material to use your texture, it’ll just show up gray.
Pretty much the equivalent of “Have you tried restarting your computer?”, but the number of time I’ve forgotten the most basic steps is just astounding…
I use Wings 3D. I export as FBX. Sometimes it doesn’t bring the texture with the model. Just import your texture into your Assets folder (I use a textures folder within Assets), and it should pick it up.
If that doesn’t work, check the Inspector for the model. In the FBXImporter, check the Materials → Generation setting.
And if that doesn’t solve the problem, attach the texture to a Material and attach the material to any instances of the model.
If none of those work, it is a problem I haven’t seen using Wings.
