Hi, thanks for the reply, and sorry for not answering sooner.

I always keep old Octane versions installed, so I just continued working on the project in the same version it was originally created in, and everything is fine there.
I mainly tried opening it in the latest version because I wanted to ...

I finally updated to Octane 31.7, but opening scenes made in Octane 30.11 + Blender 4.5 in Octane 31.7 + Blender 5.1.1 completely breaks them.

A few issues:

Materials using height maps become invisible.
If using Vertex Displacement, I have to disconnect the node.
If using Texture Displacement, I ...

Thanks for the responses. Sure, it’s not a top‑priority issue, but it would be nice to have it "fixed" — the Chaos Texture is a really cool node, and it would be great to be able to use its full potential.

I can share a material setup that is causing problems (I cannot share the full scene because of NDA). In that scene, I’m using this exact setup for three or four different materials with different textures, and whenever I switch to Chaos textures, the issues start to appear


Octane_Ubermaterial ...

Hi everyone,

I’ve been experimenting with the Chaos Texture node and ran into a problem. I’m using several Chaos Texture nodes with identical settings to drive multiple bitmap maps for a material (around 6 maps per material). However, when I add multiple such materials into a scene, the render ...

If storage and optimization is "absolutely not a concern", then all the above isn't much pertinent but on a technical level, valid.
In my case storage - is one of the last concerns as renders (even 32bit exrs) take maybe 10-20% of the overall project disk space.

That's a common misconception ...

OpenEXR at 32-bit is technically unnecessary for outputs other than data AOV.
I'm talking only about still images now. Not video sequences. And yes, I'm using AOVs in post, so I do need 32 bit exr. And the images get printed, so sRGB is not a best choice for me )

Maybe, I'll use Octane compositor ...

Thank you.

I'll try it out with AOVs feature.
It was pretty challenging for me to find a way to achieve color consistency between applications in my workflow (blender octane -> 32bit exr -> after effects -> 8bit -> photoshop) on my monitor, and setting ACES:Rec2020 in OCIO view is essential step ...

I've tested it at my side - it works fine in 29.18, but does not work in 30.0 beta1. So I think there really is a bug in 29.19, that were trasfered to 30.0

Hello, I can not change OCIO views on Blender Octane 29.19
I can change views, but it has on effect in a viewport.
It works as it should in Octane standalone.
Can please somebody check, if you have this issue too?

It worked fine at my side in previous verisons.
Thanks
