Shaders not Working
-Using ATLauncher
-Using Minecraft: Remade & Remastered vers 1.21
I've tried using all of these shaders here and each one does not work, and it says in the chat to tell Iris the issue and to "copy this" so i keep getting this error when i try each of the shaders in the screenshot.
Mixin transformation of net.irisshaders.iris.pipeline.programs.SodiumShader failed

can you send a log
How to find crash reports and logs
Consider uploading your log or crash report to https://mclo.gs/ then sending the link to it in Discord. This makes it much easier to read the logs and it even automatically hides critical information like your IP address!
If your issue involves a game crash, please locate the crash-reports folder in your .minecraft directory and upload the relevant crash report.
If your issue does NOT involve a crash, or there is otherwise no available crash report, please locate the logs folder in your .minecraft directory and upload the file named latest.log

I think it's caused by Chunks Fade In
ah wait :ioa:

your iris and sodium are extremely outdated
how do i update it?
oh wait
i dont think i can because the mc remastered modpack im using is 1.21
š

sodium 0.6.13 and iris 1.8.8 work on 1.21
oh okay. do i just look up the links and download those versions?
your launcher may have an auto-update feature, otherwise download the files from Modrinth/CurseForge and put them in your mods folder, deleting the old versions
