It has come a long way and we are happy about it thanks to you.

Regarding the IPR I have these notes:

1) Scene Update (Functionality)
Under the the "Update" tab there's a selection of objects to check for scene update like: camera, lights, materials, etc.
I noticed they work correctly when hitting the "Update Scene" button and the scene updates only the selected ones.
But when the scene updates due to changes in the viewport or in parameters of the camera, objets, or renderTarget (manipulating the scene); all of the objects under the "Update" tab are updated regardless if any is unchecked.
I don't know if this was the purpose or not.
But I personally wish for the "Update" objects list functionality to work also when manipulating the scene and working interactively for faster and efficient working.

2) IPR Color Sampler (Feature Request)
It would be great to have a color sampler in Octane's IPR which shows scene linear RGB values.
It's efficient and necessary to light matching CGI and lighting to Footage Plates.

3) MPlay Snapshots (Feature Request)
Octane IPR Snapshot Gallery is a good addition and can store and compare not only Beauty passes but also other AOVs. Which is great.
On the other hand, user may still use "Save Image to MPlay" because of missing image tools in Octane's IPR like mentioned above in (2).
Currently, Snapshooting to MPlay only take the "Beauty" pass not matter what AOV is selected in Octane's IPR.
It would be great if "Save Image to MPlay" takes into account what AOV is selected (or snapshots all the AOVs to MPlay and from there one can select which channel to view).

I already reported this bug via a support ticket, but will drop it here too:
Volume Motion Blur doesn't work with Standard Volume Shader.
I am waiting on this fix, it's much needed. I hope for the next build if possible

Otherwise your octane IPR will just be a black rectangle.

This is on a scene with just a cube and a camera. Karma is able to render with the GPU, as is Octane Blender, so for now I am reduced to playing with octane on my M3 Macbook Air, which actually performs surprisingly well.
Can anyone confirm this version running successfully on linux?
