Hi, first of all I am a fan of Octane render and I am not a super pro user.
I used Octane Blender in Intel macs and was ok for my requirements, but since I changed to M1 I noticed it is faster rendering, unfortunately there are so many glitches even from an interface level that just pushed me to use Blender3.2/cycles.
The glitches I encountered are; being unable to select or transform/move objects from the viewfinder (just able to to those thing via menus), the top menus usually are overlaid between themselves so the UI is not right, and as far I understand that the denoiser is not working in M1 properly yet.
The above glitches slow down the workflow, so sometimes I just bring down very simple files from Blender 3.2 to render them on Octane, knowing I will have to re-do materials
Hope to find the solutions to those glitches and hope Octane is available soon for newer versions of blender.
Cheers!
