Iris failed to load shader!

I got the message net.minecraft.class_2973: Invalid shaders/core/basic.json: Non [a-z0-9/._-] character in path of location: minecraft:basic_tessControl.tcs When trying to load any shader. My version is 1.21 using Fabric Essential and I have quite a few mods.

Send game logs.

How to get a log file:
Game logs can be found in the logs sub-directory in .minecraft on clients, or the logs sub-folder of the server directory for servers. We're probably interested in the file named latest.log, which you can drag and drop into Discord.

It appears this is an issue with Euphoria Patches shaders. Forward this to the developer if you have contacts for them.

:thonkwithshades: Does the issue go away if you disable shaders or using other shaders that are not part of the Complementary family?

The Thanos Method What is The Thanos Method? - The Thanos Method (more accurately known as a binary split) is a debugging technique used to find the mod or mods that are causing the issues you are experiencing. How does it work? - The Thanos Method is simple. To find the conflicting mods, split your mods folder into 2 groups. Remove one group, and test in-game. Keep the group that has the problem, and repeat until no more mods can be removed without the issue disappearing. Thanks to The Thanos Method, you can now enjoy an issue free modded Minecraft! https://cdn.discordapp.com/attachments/731716903742996531/873271100602220584/2951.1490520804.gif
