I’m sure this was posted somewhere through here but here is my problem. I’ve saved some models in Maya and am trying to import them into Unity. I export them as .fbx files and place them in the project folder. When I try placing the model into the hierarchy or onto the scene screen the model is not visible. I can move it all around, even scale the model, I just can’t see it. I tried saving the files as .ma or even .mb. I’ve tried everything I can think off to correct this issue and still nothing. If anyone else has had this issue, or knows what is going on I would really like your help.
Can you see the model in the Preview if you select it in the Project Pane? Have you done a simple test with a cube from Maya just to see if the simplest model can be imported? Is the scale set to 1 in the import settings? Are all the Layers turned on in the Layers menu in the upper right corner?
No I can’t preview the model. I thought it might have been Unity so I tried a prefeb asset and that worked ok. I have done a simple cube test and still the same problem persist. The scale is set to 1 in the import settings, and the layers are all checked in the right corner. Thanks for the reply though.
Make sure your normals are right- in maya turn off two sided lighting if your model turns black- select it select faces and select them all then goto normals and select reverse-
Be sure to turn two sided lighting back on-
I doubt it’s a normals issue as he’d still be able to see some portion of the imported mesh.
What version of Maya are you using and what version of the FBX plug-in do you have installed? Are there any errors in the Unity Console when importing?
its Maya 2012 and the plug in is FBX version 2012.1. There are no errors when I importing into unity.
Try manually exporting with FBX 2011. If that doesn’t work can you post an example file here and I’ll have a look at it.
ok I really appreciate your time and attention on this issue. I’ll try those and if no luck I’ll post an example
ok I tried exporting it with fbx 2011 and no dice. I’m not sure how I can post an example on here. If you have any suggestions, I’d be happy to try it
Go to the advanced reply and attach a file. Or just send it to me directly at “ethan at unity3d dot com”.
I had a look at the file and the problem is that you’re using nurbs to model your objects. Fbx should be able to translate the nurbs to polygonal meshes on export but this isn’t happening. So before exporting you need to convert your nurbs to polygons… or simply don’t use nurbs at all 
Ethan… thank you so much, that did the trick. You really made my day with your experience :). I never thought of making my models in polygons a pose to NURBS.I thought it was both Maya and Unity failing but good to know that they both work ok. I’ll have to figure out a resolution to the FBX exporting problem, but for now I can convert my models to polygons. Question though, will I lose resolution using polygons instead of NURBS?
If you tesselate the geometry properly when converting from nurbs to polygons it will look similar. If you’re going to get into modeling for games though I’d recommend moving away from nurbs modeling and try to do more of it with polygonal modeling from the start.
I will definitely take that advice and start building everything more with polygons. Once again thanks
