@gri573 (Rethinking Voxels) Might want to check it out.
thx
will they respond?
It should allow you to copy the error and send it here
Please do so, or I won't be able to help you
That is the error it copies I believe
@thinderfg could you send the full log? If you can recreate the failed shader load again it will be in latest.log
whre would the log be?
it said to copy this shadowcomp compute shadowcomp1_a!
Logs folder
where would i find that?
i also am using a aspire acer laptop
i found the logs folder
Nice. It's called latest.log, and it only contains the error if you didn't restart the game since you got it
is the logs in the minecraft folderss?
sry if i am being confuing
actualy i found the latest logs file do i coppy it and paste it in here?
like the whole thing?
drag and drop it
wait i am sorry how do i do that?
it is in notepad should i just copy and paste it here?
here
wow that's sad
(the driver doesn't support compute, but failed to say so in the OpenGL list)
You should try updating your gpu driver, your GPU is supposed to support up to OpenGL 4.6, which includes compute shaders. I am intrigued by the fact that shadowcomp1_a triggers the error, as there are multiple compute shaders in shadowcomp before it
Idk my laptop it old it’s about like 4 years old

What graphics processor and driver do you use?
I don’t know I can check when I get back home
You're getting a shader not supported by hardware error.
Oh
So it either bad drivers, need to update drivers, or you use a very outdated GPU.
Perhaps even the forcegl20 mod might help you.
Okay should I check my gpu?
Radeon Vega 3 iGPU.
Thats what you got.
Is that good?
Its built into your processor so no.
Ooh
Its also one of their lower end skus.
In that catagory.
Ooh
But it should have the correct support to run the game.
I can run Minecraft fine
That won't apply here.
Since its clearly a feature a mod added thats not supported maybe the shader itself.

You can try ForceGL20.
For your mc version.
It might work.
I am also using Minecraft 1.21
Okay but it is a shader problem not iris problem?

This is the newest AMD Driver you can try that as well.
Seems to be hardware or shader based on log.
Using ForceGL20 and new drivers isolates for hardware.
If it still happens after that it has to be an iris thing with AMD iGPUs.
How would I do new drivers
you find them and install them
Where would I download new ones
you'd have to google that
Okay
Guess I'll take a dip into this issue page.
:facepalm:
Classic case of outdated GPU driver.
