CUDA Error

[Cazure95]

I'm terribly sorry for starting this many threads on the forum regarding issues I encounter.

But I can't get my head around this error. Especially I didn't see it anytime before. And it somehow disseapered.
While rendering I'm getting a CUDA error, this comes out in the log:

I don't know if I miss V-ram, but I got it working on my setup yesterday, so I don't know why it shouldn't now. I don't have any new textures of anything like that.
I'm working with a GTX 770 + 980. I've updated the drivers from the NVIDIA website. But that didn't fix anything.

Of topic, you have propably two octane dlls. Remove one.

Code: Select all

This means that an error occured due a limitation of Cuda renderer. Octane can't handle triangles than more 19millions. Check your triangle counts.
Also your scene should fit to VRAM. I see 19sec. for material export. Most likely you have lot of materials and textures or very big textures. If it's related with not fitting of textures to VRAM, activate out-of-core option. So textures can be used from System RAM.
