I was rendering an animation when this problem occurred (CUDA error: Launched failed in cuCtxSynchronized(.) ). I know next to nothing about the technical side of blender. I have tried looking for a solution online, but haven’t found a conclusive answer. Can someone help and explain why this happened?
thanks for replying! The tiles I’m currently using are already reduced by a large amount (the exact number slips my mind. I’ll post again when I can get the file). I lowered the tile size to reduced render time for this animation and it seems to work fine until halfway through.
I had this error for the first time just recently. It happened when I linked or appended an object with a volumetric texture. The same object in it’s original file renders on gpu with no issues. I might try to reproduce it in a simpler form for a bug report.
Could you give more information? Graphic card? OS?
Does the problem occur with most scenes or with a particular scene?
Could you share the scene? http://pasteall.org/blend/
I reduced my tile size from 512 to 100 and it sort of fixed it. It’s rendering but at a slower rate. I’m going to fidget around with tile size to find an optimal balance to get a faster render time. Thank you for your advice! It really helped
Sometimes in windows when you use the same card to display and render, some CUDA errors appear if you are using Branched Path Tracing. But if you do not know what it is, you should be using Path Tracing which is by default (Render tab > Sampling).
