Is there an error in Out of Core display? VRam is full, System Ram filled with 100GB. But display says all fits into VRay. I set head room to 512MB. Also the rendering speed "feels" like there is OOC used. It's slower than usually.

Yes and this is the connection I don't understand.
In my understanding when setting it in preferences, all new materials or loaded m aterials will load with this setting. I tried "default". But don't work.
I also know the place to switch the color space per texture like in your video.

I have problems with Color space. Its's set to sRGB in Octane Preferences.
But some of my models import (mostly Xref merge) end up with Linear sRGB. So my textures are very bright.

Even when I import a new model, convert the materials from Corona or VRay to Octane it's getting bright right after ...

BUG:

OctaneLight has no size when opening a scene from Octane 2025. But it is displayed with proper size in viewport. Had this in several files now.

Thanks. I thoughts it's a problem on my side with the Corona Update I did. Glad it can be fixed!

I did some manual adjustments for now. Corona Materials are very shiny usually with a roughness set to 0.0 all the time, which makes it neccesary to adjust them all one by one after first conversion ...

I made upgrade to this version and also updated to current VRay and Corona renderer. I don't have license for them and never use them but as far as I know they are needed for material conversion.

Now I have problems that the material is unsupported. But it used to work for years before. This is ...

I lost the overview a bit here in the threads.

I'm still running 3dsmax 2024 because of all the lagging reports with newer versions. So also on Octane 2025.5- 16.12.
Reading here all the posts it seems its a bit dangerous for updating to latest version? Especially if I render out of core with ...

There are issues and crashes with 360° panoramic renders. I had no time to track them down in which combinations they make Octane crash due to an ongoing project.
But reverting to the latest pre-2026 version made it work again.

Thanks for the support. It doesn't work when I use the "Support Type: Legacy", right? At least for me.

My two 5090RTX also don't go up to 100% but no in terms of power consumption and heat. They consume mostly around 300 Watts per Card. But deliver full performance in terms of clocking.
In Furmark the go up to nearly 600 Watts power consumption.

The "internet" says it's because of the utilization ...
