importing nurbs model?

mike_n

Does the FBX content importer support nurbs models I exported a simple sphere in Maya 8 as sphere.fbx, but the content importer throws an exception when it tries to build the asset:

I saw a reference to a function trying to import animations, however the object isn't animated at all... I can provide the asset somewhere if needed.

BTW, I re-exported as a polygon model and all is fine...

Correct, We don't support NURBS models only polygons. Maybe we can do something in the future with that error though. Thanks for letting us know!

Thanks!
