I recently switched from Windows to Manjaro because i tied it for some time on my laptop and really liked it.
But now I have major problems with blender 4.0 Cycles HIP rendering on my PC. I tried amdgpu-pro-oglp, hip-runtime-amd and hip-runtime-amd-blender but i get strange shading with progl blender and hip-runtime-amd-blender, with hip-runtime-amd blender crashes when selecting gpu rendering. I use a "radeon 5600 xt" GPU and everything worked fine on Windows, but i really don't want to go back to Windows
Everything works fine in blender 3.6 LTS I created a simple scene to show the problems on the left is simple principled bsdf, middle left is principled bsdf with full SSS the sphere is metallic and the cube on the right is glas:
- Blender 3.6 (GPU HIP, works fine thats how it should look)
- Blender 4.0 CPU rendering (works fine)
- Blender 4.0 GPU (HIP, not working, sometimes crashing)
Pls help its pretty important for me that newer versions of blender work. If you need more information just ask.
I have a NVDIA GPU and no idea what could be the problem here, unfortunately. The only thing that comes to mind is that when you bake textures you need to disconnect the metallic node or turn it to 0, otherwise the bake will be completely black. No idea if this is related but it looks like it might be a problem with reflection?
You tried to uninstall and reinstall the GPU drivers? Are there different versions of the drivers (for NVDIA there are) that you could try?
i tried different drivers, nothing helps have reported the but to blender, seems like some other user has the same problem https://projects.blender.org/blender/blender/issues/115957
Ha, if they're aware of it and others can reproduce it, then hopefully there will be a fix for it eventually.
