Maya freezes Unity and vice versa.

Hi! When I save a maya(.mb) file into the model folder of my unity project Unity freezes. I just can't save maya files to the model folder. In some cases I actually saved it but when I moved the model to the scene only the pivote of the model was visible. Sometimes when I tryed to save maya files into the project folder a window appeard and it said that maya doesn't respond and will be closed. How can I fixed? What may be the problem?

Try saving your Maya files as Maya ASCII (.ma) as opposed to Maya Binary (.mb). Maya binary files generally work poorly with other apps outside of Autodesk software. Also make sure your model use only polygonal geometry. I have seen some objects with rigs or controllers only with the mesh invisible because the geometry was based in NURBS.

Try this and post if it makes a difference or not. Best of luck!
