From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Blender 4.0 Problems pls help ;-; (lemmy.ml)

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:

  1. Blender 3.6 (GPU HIP, works fine thats how it should look)

  1. Blender 4.0 CPU rendering (works fine)

  1. 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.

https://devtalk.blender.org/t/cycles-amd-hip-device-feedback/21400/542 I’d test 4.0.3 or 4.1 from the build bot https://builder.blender.org/download/daily/ to see if this is fixed or not. Then report a bug to blender.

That doesn't look right. But I haven't tried 4.0 yet. Let me check.

I don't know Blender, but from experience I found that Manjaro/arch is a bit too bleeding edge for production use. Especially when it comes to non-gaming graphics. I experienced a lot of problems with Manjaro and GPU acceleration in video editing suites. All got solved when I switched to Linux Mint.

Similarly Zorin OS 17 has been good to me. I really like their approach to the Gnome UI (i.e. they kept the newest tech, and removed the space wasting UI components.

The Ubuntu based distros typically have fewer bugs as they typically have an older base.

Fedora is also a decent middle ground.

I would suggest logging a ticket or forum post with Blender on this. It could be a blender bug or a graphics bug, but they would be the best people to advise.

Could it be that the manjaro repos have older versions of the HIP runtimes then what blender 4.0 is built for? Just a thought. Either way I would report it to the blender devs so they can fix it if it's a bug

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?

[–] [email protected] 1 points 9 months ago

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

Did you try the Flatpak version or packages of other distros (like Fedora) via Distrobox?

You probably installed it on your Manjaro install via pacman, did you?
Sometimes, the native packages are just missing some additional elements and then only kind of work.
