Blender crashes when rendering this file on CPU and GPU
Closed, InvalidPublic


When rendering on any frame higher than number 8. Blender chrases automatically on CPU and GPU. I have tried eliminating different options such as motion blur, etc. But the crashes repeat. Doesn´t happen when you do an Open GL render, so I guess it´s just a cycles thing.

The file needs the Animation Nodes addon 1.0. You can download on :

Maybe ist also a bug in my addon, because when I remove all nodes it does not crash. I will try to simplify the file later today.

Well the thing it´s that only happens when rendering with Cycles or Internal. AFAIK works perfectly with Open GL rendering

yes. maybe my code leaves the mesh in an invalid state or so. I don't know why that happens sometimes and sometimes not but thats another thing.
At least it would be helpful if you could also try to simplify your file.

Does this happen with loading factory settings without animation nodes? Because it is likely a threading issue which is on the to-do list.

This is the traceback I get from gdb. (note: this is my first attempt to debug blender)

Oh and now I'm getting another error:

I have no idea what causes this crash but maybe you are right..

Another file with the same issue.

The thing agains is that only happens with cycles rendering. Open GL works perfectly.

Can you try to use the scene simplification to disable the subsurf modifiers in the viewport?
That seems to solve the problem on my pc..

Aaron Carlisle (Blendify) claimed this task.

It seems that now one could reproduce this without the addon. Sounds like a treading issue which alot of addons have with blender which is something that can be improved in the future
