Shader compilation failed, see log for details

When I try to enable Complementary Reimagined shaders on Iris Neo 1.21.1, I get this message: Shader compilation failed, see log for details: https://mclo.gs/OIPgBeO Perhaps they are incompatible with this resource pack? Or perhaps it is incompatible with them... https://modrinth.com/resourcepack/angels-weather...

Elytra Trims not working

Hey! I'd like to use elytra trims and iris shader on fabric 1.21.10 - my problem is that the elytra trims are not rendering correctly with iris and making them look red in color, do you think of making it compatible with elytra trims? The mod is very cool and i dont wanna miss out on it just because of iris! Thanks!

Shaders menu is empty

See attached screenshot. Log doesn't seem to say much about this, can attach if needed. THis is after clicking "Shader packs..." on Sodium menu Mod list: https://pastebin.com/UbRuFY47 Neoforge, 1.21.1...

Solution:

Disable background blurring in the accessibility settings.

Duplicate lines on fishing rod

When vanilla fishing rod is used then put into offhand and then fishing rod from other mod is used (which works differently and doesnt have ItemAbilities.FISHING_ROD_CAST) the vanilla bobber then connects to the fishing rod from another mod This doesnt happen without iris so i assume its a bug todo with iris. Is there anything that might be causing this i can do in the other mod, development wise, to solve this?...

Solution:

this is caused because of line strips having no default primitive restart

Creating Mod Compat for custom mods

Heyo, im working on a 1.20.1 Fabric mod right now where im making use of internal shaders... I have made my peace with not being able to have players experience them next to their prefered iris shaders but at least I want to toggle the active iris shader for the duration of my own internal shader if possible. I found this method which looks like its doing what i need it to do, but from what i know there are no public maven repos for iris? Going over the Modrinth Maven brings in a lot of issues especially with Sodium being a requirement and their libs not being as transitive as I hoped... ...

Minecraft crash when using shaders 1.21.8

My minecraft crashes when i try to open shader: this is my log file(only the part when i started to click on shaders)(at least i think so), my mods include:

Solution:

Seems like the shader pack zip file is corrupted? And seems like the game crashed because Iris tried falling back to normal rendering after that but triggered a state exception. I'll suggest re-downloading the shader pack and see if it solves the issue.

Whitescreen when opening F3 menu

This only happens when shaders are enableda and when I'm on fire. It probably has something to do with the color space, because I have it set to DCI_P3. It also appears when setting it to other color spaces except sRGB....
