Assuming you are using windows - Have you tried to duplicate python3.xx folder and rename it to python3.11 ? In this location - C:\ProgramData\Thinkbox\Deadline10\submitters\Houdini

Sorry for the late reply!

Submitting works, and it also starts trying to render. But i then get errors in deadline.

They look like this:

=======================================================
Error
=======================================================
FailRenderException : Error: 'const ...

Not really, no. What error do you have or what doesn't work for you? Maybe I can share some pointers or tips - Deadline install is pretty straight forward - after that connecting the Deadline ROP to Octane ROP and submitting.

For the above screenshot - we had - Octane_2025.2.0.0_Houdini_20.5.550_Studio+_Win64

What is not working regarding Octane and Deadline?

Here is working fine with 2 workstations.

Thank you for coming back with the solution. I appears that turning off the Ai Light also solves the problem with a lot of instances that have emission material on them.

Thank you - While they are looking exactly into this one - besides moving the light with heavy geo in the scene - Also it seems that octane can't load after a certain number of instances - Geo that is instanced and has emission material on it. Could you please also look into that?

Please do - I always try to do a whole project in Octane from start to finish and I always find some little quirks like this - that make it impossible in the middle of the project.

Sure. Please find attached a scene for test - it's just a sphere with a light. I've made the scene with OctaneRender 2025.1 - but as I can see in OctaneRender 2024.1.2 it says "Improved slow IPR update when moving object with lots of polygons" and in 2025 it says "Includes all fixes in 2024.1.2.1 ...
