Does it crash with every scene? If it is a specific scene, can you upload it please?

[Stugys]

strange, looks like it is one specific scene, just a second will be transfering it.

[Stugys]

sorry for big scene 1.2Gb

[poseidon4o]

Stugys try with next nightly build (tomorrow), this crash should be resolved.

[Stugys]

Thank you very much!

good evening, its me again, in 2017 11 30 build blender works fine, no crashes, if you know there is addon for blender LoopTools and looks like it is not working with mentioned date blender file, when i disable and enable in addons tab it gives python error message. It works with blender oficial releace and with blender build bot vertions, so i just thought maybe it is something wrong with vray blender build. sorry if i am wron, here is python error message:

Hello, is any body alive here?

LOL, you're the only activity in this subforum for a while. It has been pretty quiet in V-Ray for Blender world.

[Stugys]

Look like that was just calm before storm of posts

This means that for some reason you have a copy of addons under your user directory.
Try removing everything from "/home/User/.config/blender/2.79/scripts/addons/" (may be even from /home/User/.config/blender/2.79) except stuff that you have actually installed yourself.
