Issues downgrading Blender [FIXED]

Hello,
I have been using Arch actively for around a year and a half now and I have recently decided to install it on my side machine, which is a fairly old (~2012, upgraded with a bit more ram) desktop which I use when I can't use my main (for reasons I won't get into, happens pretty often).

Before installing Arch, i had Debian on it, and ran Blender 3.4.1 without any struggles. When Trixie came out recently, I held Blender back from upgrading as I knew the pretty awful IGPU in this computer did not support OpenGL 4.3.
When I switched to Arch, I tried doing the same thing. I checked the page for downgrading packages (https://wiki.archlinux.org/title/Downgrading_packages), tried around a bit with that, and ended up using a fairly simple AUR package called Downgrade, which is just a simple bash script, so it just automates the manual process.

I tried running Blender a couple times, but it was not starting up. I finally tried from the CLI, where it said:

blender: error while loading shared libraries: libosdGPU.so.3.5.0: cannot open shared object file: No such file or directory
(I'm sorry if I didn't format it properly, I tried using backticks but it did not work.)

No biggie, I went looking around on the forums; and found a post talking about my exact problem (for the love of god, I cannot find it anymore). The fix for it was fairly simple: downgrading a package called opensubdiv to 3.3.3, instead of the version 3.4.0 they were using.
Now here comes the real problem: the opensubdiv package on the Arch Linux Archive (https://archive.archlinux.org/packages/o/opensubdiv/) only goes back to 3.4.0.

This is infuriating because I was so close to solving the issue and it's so annoying having to bother other people for this kind of stuff but aaaa!!!
I guess the only solutions would be either finding someone who still has the pacman cache of opensubdiv 3.3.3 (if I am understanding correctly how this all works) or finding a Blender version with no problems and that would work with my IGPU.
In case anyone wants to help with the latter, here are the results for my IGPU when using vulkaninfo.

GPU0:
VkPhysicalDeviceProperties:
---------------------------
    apiVersion        = 1.2.318 (4202814)
    driverVersion     = 25.2.5 (104865797)
    vendorID          = 0x8086
    deviceID          = 0x0f31
    deviceType        = PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU
    deviceName        = Intel(R) HD Graphics (BYT)
    pipelineCacheUUID = 7912a5a0-48c2-b39b-decc-bd12d9ff1c9d

(Again, so sorry about the formatting, if someone can tell me how to format stuff properly I'd be very happy. Also, I am pretty sure I installed all the necessary drivers, am using acceleration, etc but if any of you need outputs for vainfo and such don't mind asking.)

Re: Issues downgrading Blender [FIXED]

This is what's known as a 'partial update', and is not supported in Arch. You could easily end up downgrading more and more things until your system is unbootable.

If you need an older version of Blender, you need to build it yourself, not use an old binary package. If it won't build against current libraries, you'll need to build those, too, and install them in a *separate* location that the rest of the system won't load them.

Re: Issues downgrading Blender [FIXED]

Grab it from https://download.blender.org/release/Blender3.4/. Extract, cd into the extracted and run with

./blender

It should run from there - all libraries included. (I just tested on my fully up to date system and it ran no problem). It doesn't need to be installed.

NB. This is an official release from the official source. Not some hacky third party release.

Oh, thank you very much. I'll go do that and reply as soon as possible.

Re: Issues downgrading Blender [FIXED]

Seems to be working perfectly fine, atleast from the couple minutes I used it. Thank you Roken!

I guess I'll go and mark this as solved now.

Re: Issues downgrading Blender [FIXED]

The blender from the repos should work just fine, I tested it on my laptop a bit ago, please install it with a full upgrade and try again! (pacman -Syu blender)
