Re: Film-only out-of-core rendering support (CUDA-only)

Please don't straw-man me. That leads nowhere. You replied to/quoted my comments, which were an answer to the comment about OOC eventually not working on Windows. Nothing else. I always said that the FOOC works and tiled vs. progressive rendering never entered my argumentation about its validity. Th...

Re: Film-only out-of-core rendering support (CUDA-only)

I fear, we are talking past each other here. The discussion is about the technical possibility of using OOC on Windows. It should not matter if tiled or progressive rendering is used. The difference would only be the amount. For what it's worth, here are the stats for the scene with progressive rend...

Re: Film-only out-of-core rendering support (CUDA-only)

I don't see what tiled rendering has to to with the capability to use shared memory or not. And I can't use Cycles X at the moment as the GPU memory management is not properly implemented yet. It throws an error right away. And I don't mind tiled path rendering. Once it works properly in Luxcore, I'...

Re: Film-only out-of-core rendering support (CUDA-only)

With FOOC enabled the rendering of a 7200px 4800px image finished after 2.5 hours. Without FFOC the rendering aborts with an OPENCL error. So that's a success. However above that resolution is't still a no-go and Blender just crashes without any message as soon as the GPU memory exceeds my availabl...

Re: Film-only out-of-core rendering support (CUDA-only)

The task manager shows the extended GPU memory (38GB here) and Cycles clearly uses that overhead when you watch the numbers going up during rendering.

Re: Film-only out-of-core rendering support (CUDA-only)

I was wondering the same. But as the memory consumption on my Windows machines wasn't affected by the "old" OOC, I have also left it unchecked now. And Windows seems to support OOC (in Cycles anyway), it's just nor supported in Luxcore for Windows.

Re: Film-only out-of-core rendering support (CUDA-only)

Oh. This could be huge. This was one of the big hurdles for me to move to Luxcore for production. I hope that this will free enough memory. Cheers.

[EDIT] The rendering started, which wasn't possible before. That's good. Resolution 7200px x 4800px. 6GB/GPU (maxed out), 20GB/32GB RAM used.

Re: Texture caching... amazing improvement in memory with Cycles, could be great in LuxCore!

I also wonder if render passes are kept in the GPU memory at this point and if so, if they can be move to system memory. This might allow to render higher resolution renderings.

Re: Texture caching... amazing improvement in memory with Cycles, could be great in LuxCore!

Every option to get around (GPU) memory problems in Luxcore already suffers huge performance hits, loss in quality and often doesn't work at all (like out of core). You might maybe want to keep an eye on this development and if it's stable, you can ditch "Tiled Path" and "Out of core&...
