Thanks!

Thank you so much!

Dear team,

I found that there is a significant change from 2025.3 to 2026.3 in how Octane handles collection instances.

In 2026.3 the Octane Object Attributes of the individual objects in the instanced collection are not passed trough anymore.
Instead the Object Attributes of the instance object ...

No, it does not

The developer of HDRLS told me that they currently do not support Blender 5.1 - just up to Blender 5.0, because there is an issue with Blender 5.1 on Mac OS, which hasn't been resolved yet.

Thanks a lot for your reply!

It is just the latest release of HDRLS + Blender Plugin. It worked fine with Blender 4.5 LTS and Octane 2025 and does not work with Blender 5.0 and Octane 2026 anymore.

I guess that it is a simple issue, because the link between HDRLS and Blender is just a temporary ...

Hi team,

when using HDR Light Studio with any of the 2026.x plugins the temp HDRI does not refresh automatically anymore.
Platform: Mac OS X 26.5 on M4 Max

Could you please fix this?

Hi team,

today Mac OS 26 will be officially released.

Is the latest Octane Render tested and ready on Mac OS 26 (on Apple Silicon)?

Thanks in advance!
David

Hi,

I usually achieve this with a specular material.
Refractive index set to 1.0, reflection color set to black, then just adjust the roughness and that should be it.

Hi team,

I have an internal benchmarking scene for our computers and I cannot believe my eyes.
M4 Max with Octane 2024.1: 39 sec.
M4 Max with Octane 2025.1 Beta: 24 sec.

How did you do that?!
Incredible work!
