Blender Crashes, Causes Unity to Crash
Closed, ArchivedPublic


System Information
MacBook Pro Retina 2.6 GHz 2012
Blender 2.71

Blender crashes whenever I try to export any format except .obj. Also, last week I was importing objects with 1.6 million plus vertices into Unity from Blender, with no problem. Now, anything with more than like 1 thousand vertices crashes Unity, and Blender can only handle .obj and .blend, no other format.

Try to export other formats, or try to get super high poly objects into Unity, to reproduce the error. I'm using the latest versions of both Blender and Unity.

Tssst… First of all, if Unity crashes, it’s a Unity bug, not a Blender bug!

Further more, we need a file you are trying to export, and which crashes Blender.

Third, Blender supports tens of other export formats, like FBX, DXF, collada, whatever…

It actually may not be a Unity bug if something is corrupting the file in Blender, which in turn is crashing Unity. Furthermore, FBX crashes Blender on its own.

We can keep talking about that endlessly, if we do not have a file to check…

5 days without reply. We can not fix bugs which we can't reproduce. And to reproduce the crash we need as small as possible file demonstrates the crash with minimal steps to crash.

For until this info is provided archiving the report.

It is fairly simple to reproduce this issue. Just place a .blend file in a Unity folder and see how it crashes. This seems to be cause by Python as described here:

@Bastien Montagne (mont29), thanks for pointing me to the correct one!
