Blender 3.5 on macOS Issue

LightStudio can't be activated on macOS using Blender 3.5.1:

Sounds like cross-platform shader generation needs to use the new gpu API that supports Mac/Metal.

What should be done to fix the problem?

this file should be pasted to the text-editor and executed, like descirbed? https://docs.blender.org/api/current/gpu.html#triangle-with-custom-shader

That doesn't change anything for me. It is still not possible to activate LightStudio on a Mac and Blender 3.5.1. I would love to use it on the latest stable blender version. Will this issue be fixed in a future release?

[leomoon]

We are working on a fix to support Metal on macOS but by changing GPU Backend from Metal to OpenGL you can use LightStudio on macOS until we have a fix.

• Open Blender
• Go to Edit > Preferences > System
• Change GPU Backend to OpenGL
• Close Blender
• Open Blender and install LightStudio

This is fixed in the new version.
