Segmentation Fault 11

[jkontiola]

I get this error when trying to render a specific project ive been working for multiple months now.
I already posted about it in a thread I posted about Caustics making render darker. I propably shouldn't have posted in the same thread about the crashing but i thought it had something to do with the caustics because i was just playing with the caustics settings when the error started.

Im so greatfull if anyone can help.

Here is the error log:

seartch in blender vray section for key word nightly builds

i was using newest nightly build. I also tried previous version but it crashed too. The newest build is supposed to be 2.78 but it says 2.77 in the splash screen. I wonder why

[jkontiola]

I got it working again. The crashing seem to occur because of some material that wasnt even used. I dont know what was wrong with it. Just happy that got it working again.
