About2016103916, Some problems do not know have you met?

Now there are several issues:

(model is not very big, my post from "test 360 Panorama")

1, adjust the model texture too much, especially add normal mapping and bump mapping is complete, save and exit the software, open a previously saved document again, if you want to change the material properties of the document, they may fail or crash.

2, fine adjustment of materials, save VR movies, may also cause the system to crash.
