Iris 1.8.0 for 1.21.3 crashes my game when I join a world. Why is this suddenly happening?
I only have that, sodium, and fabricAPI
fabric | iris 1.20.1 ver. 1.6.17
hello, I've downloaded iris ver. 1.6.17 with sodium ver. 0.5.9 and it kept on crashing upon loading up a world (whether new or existing for mc 1.20.1)
is there a fix for this?...
Glowing texture overlay
Is this an iris issue or is there a json command to block the texture overlay to glow above an emissive block?
I already tried
"emissive_ambient": false
and it's not working....
1.21 Iris Shaders keep crashing my game.
Hey, I just upgraded my PC (bought a new one) and everytime I turn on shaders my entire Minecraft crashes. I haven't had this before so I'm pretty confused.
Iris + EMF drops the fps horribly
While developing my resource pack with a collection of mods that replace Optifine, I encountered a problem - when spawning 30+ zombies from my resource pack HIDYK's REALM (2.14.11, update in progress), the fps dropped to critical levels below 10 fps because of the models of the mobs, to which several textures are applied at once.
As it turned out the problem is in Iris, because without it there is no such problem at all. This also happens in Iris 1.7.1 and Sodium 0.5.9.
Traben helped me to find out the problem, so all further dialogues about more complicated aspects should be conducted with him. I could provide a snapshot of my resource pack, but to be clear, it was not published anywhere before the release....

F3+T (Reload Resource Pack) breaks armor textures?
I have a resource pack that I am using and whether it's using replay mod or just testing things with the resource pack. It's seems to be specifically leather armor textures. I have tested on versions 1.19.2 and 1.19.4. Haven't got a change to test on the newer versions yet.
I did find this reddit post on it. From what I read it's sodium and iris but no solution yet?

Shaders Not Working (IRIS Encountered An Issue Trying To Load The Shader)
Shader compilation failed, see log for details
Very Noisy Output
My shader output is filled with the kind of noise you can see in the attached screenshot. The noise is per-block-face and "stable"; it will repeat patterns over frames.

incompatible mods
How do I fix if its the right version but its not compatible?

Solution:
Are you using shaders? If yes, then you can safely remove Nvidium. Nvidium only works with shaders disabled. It does not work while shaders are enabled, plus I don't think you're playing Minecraft with shaders off for over 20% of the time.
