Resource packs won't load after 1.16.11 update on 1.20.1.
Just what the title says. Anyone experiencing this?
How to do back to older version?
I updated Iris and now my game won't open because of several mod conflicts. I want to go back to the version I was on before but I can't figure out how to. I am still using 1.20.2 as most of the mods I'm using haven't update yet.
So far I've tried looking in the versions list dropdown in the launcher and using the old installer from my downloads folder to try to install the older version.
How can I find/reinstall an older version?...

Shaders won't load

iris on 1.20 server
Hi everyone, I am playing on a minecraft server which is hosting on version 1.20 and I need some #help please.
However I cannot find an iris version of 1.20 but only 1.20.1 and higher. Is there a solution for that or impossible to have iris on 1.20?
Thanks 😊...

Elytra model with EMF not working the same when shaders are enabled
Hey, so I made an elytra model with EMF (entity model features) that is supposed to act like a cape and I noticed that some of my animations don't work as intended when shaders are enabled with iris.
I don't necessarily think its iris's fault, but it might be useful to find out what is causing this incompatibility. I have attached some examples of my problems:
1. my calculations for y speed do not seem to be accurate...
Older iris version not working properly
I am using sodium 0.4.10 fabric api 0.88.1 iris 1.6.4 and indium 1.0.21 because of Create mod, and it unfortunately does this when LIGHTING is in effect (when i place torch, when there is any source of light...), doesn't matter if i have shaders on or off... Any ideas?

Can Iris 1.6.9/1.6.10 be used on MC 1.20? If not, why the update message?
Iris 1.6.9 needs Sodium 0.5.3 to run. Sodium 0.5.3 isn't released on MC 1.20, only 1.20.1 and 1.20.2. When I use Iris 1.6.4 with Sodium 0.4.10 and MC 1.20, it says there's an update in the game chat and Mod Menu. How can I update Iris in a way that is compatible with MC 1.20? If I am on the most recent version usable on MC 1.20, how can I get rid of the annoying update message?
And I don't especially want to update to MC 1.20.1....
I download the installer and when I try and open it it'll just bring me to save the file location
When I try to download itll bring me to an infinite loop of me saving the file location

Can't use Iris Shaders in Curseforge
For some reason I can't use Iris in my Curseforge modpack. I've been able to previously with older versions like for example 1.20.1 or 1.20. But now when it comes to 1.20.2 it does not work. The mod pack is 1.20.2 and is set to Fabric. I have Sodium 1.20.2 Fabric in the mod folder too along with Iris Shaders 1.20.2 Fabric. Why does this happen? I can't find a way around it even tho the versions and everything match up.

Iris is having issues loading a shader.
Whenever I load into the world with the Rethinking Voxels shader, I get "Iris encountered an issue trying to load the shader; please report this to Iris developers. with the Copy Info being "Shader compilation failed for shadowcomp compute shadowcomp!" I checked the FAQs about supported shaders and it said that it was supported.
