OctaneRender® 2026.3 for 3ds max® v26.9

[coilbook]

Hi neonZorglub,
I have a problem with one of the slaves. The PC rebooted and now I cannot install slave daemon anymore. It shows no GPUs even though they are present and just says closing due to hanging up. Worked like a charm before with all versions. Do you know what to do about it?

Also are 6xx drivers any good? Any advise on the most stable recent drivers?


Thank you

Hi neonZorglub,

After doing many tests we found out 2025.3 installs daemon slave great. 2025.5 and up doesn't. Can you look into it? 2025.5 used to work fine not sure what happened. The images are attached.

Hi coilbook,
You can try 581.29 Studio, they work fine with Octane.

Hi Paride,

There is still a bug with TyFlow that causes very slow evaluation times. When we have more than 30,000 fractured pieces (for example, a breaking wood simulation), the evaluation time is 1–2 minutes per frame. I'm not sure why, since everything in TyFlow is cached and the fractured pieces are only changing their positions.

UPDATE:

There appears to be a conflict between calculating TyFlow particles on the GPU (CUDA) and rendering on the same GPUs. I suspect the GPUs get clogged, and the VRAM isn't fully released, even when the memory limit is set to 1024 MB and the GPU is not being used for rendering. It is only being used as the display card. After restarting 3ds Max and resimulating using CPU evaluation, the evaluation times became much faster.

UPDATE 2:

The evaluation times gradually get slower as more wooden chunks are created. I think there is an issue with evaluation performance when handling a large number of unique fractured chunks compared to TyFlow using a single instanced mesh.

Hi coilbook,
Try increasing the out-of-core memory limit.

Hi Paride,

When will octane support itoo railclone as instances like itoo forest. Currently it eats up vram. Thank you

There is a problem with autofocus and VDB volumes. Even transparent smoke is a wall for octane autofocus.
