Hey, when i spectate a player with Flashback in spectator mode, the hand isn't rendering when I have shaders turned on. I asked moulberry (flashback dev) and he told me it seems to be an iris issue.

DH 2.3 fading
noticing that the new "fade" feature with DH 2.3 that allows seamless LOD transition is basically disabled when shaders are on.
Just wanted to shed some light and wondering if this is a bug that will be fixed later on, something shader/DH devs will have to fix, or just simply unavoidable...
DH 2.0.x Support for Minecraft 1.20.4?
I want to use DH 2.3.0 on the Server I play on with my friends, since it's the Update that added Server Side support. Unfortunately, when launching the game, it says that DH is incompatible with any Version of Iris 1.7.4 and below.
But Iris 1.7.4 for Minecraft 1.20.4 is nowhere to be found. Is there any way to get this working or at least some Iris Beta build for 1.20.4 that is compatible with higher Versions of DH?
Thanks in advance...

Sildurs vibrant shaders breaking skins, items,armor and nametags
I wanted to take some replay shots with shaders and since complementary shaders crashed my game i thought maybe sildurs will work, so i installed them, but when i applied them pretty much anything player rendering releated broke

Problem with core shaders
Hi, I know that core shaders are usually not supported by iris, but do you if it's possible to fix this problem?

Shader Compatibility
I have an old custom shaderpack derived from the chocacpic13 v3 shaderpack that ive been using on optifine for years but recently switched to sodium + iris and found out that my shader doesnt work with iris and it says that it had trouble trying to load the shader. Trying to find out if its possible to get it working with iris, I also recently had the shader updated to fix some bugs that came with the 1.17 update so maybe it has to do something with that but I dont know.
shader fails to load completely; no chat message. 1.20.4
iris doesn't show the failed to load error, I had to open the console in the launcher to see the failed to load error. the shader pack also drags into the shader pack selection screen as a "valid shader pack".
the shader doesn't technically support 1.20.4, but I fail to see how there could be much difference between 1.20.1 and 1.20.4.
shader used: https://www.curseforge.com/minecraft/texture-packs/old-lighting-old-water
version: 1.20.4
mods used:...
Solution:
apologies for leaving you on read for so long, I decided to "do my own thing", so to speak
me looking at the log sent me down a rabbit hole of downloading colormatic for the colormap shaderpack (a really good idea, apparently!), among other mods listed here (like the skybox mod) https://optifine.alternatives.lambdaurora.dev/. this has made the pack work AND work better than it otherwise would've. beta lighting! hoo-ray!
only slight differences that I can't seem to fix are the skybox not really working, and the smooth lighting on the water while still retaining smooth lighting elsewhere, which there doesnt seem to be a mod to turn off specifically. oh well. if there's possible help with those two issues, I'd appreciate it. otherwise, I've solved the issue....

Making my first shader, how do I keep vanilla shadows?
I'm working on my own shader (mostly for learning) and I want to work on it bit by bit and learn as I think of things. Right now I've simply created some fog. But when my shader is active it seems I completely lose vanilla shadows? How can I get them back while using my shader? Currently my shader directory is this:
shaders/
├─ composite.fsh
├─ composite.vsh...

Shaders rendering improperly
I'm trying to fix up a modpack that i have but when i load up a shader, almost all of them load improperly with this bug, I'm using 1.20.1 and have distant horizons.
Solution:
I found the mod conflict, it was Hold My Items

Black sky glitch
ive been getting this error for the past year and i dont know how to solve it, it appears with all shaders that are high end and with low end shaders the clouds just disappear instead, i got no idea what causes it, ive played other versions of minecraft, without any mods etc and it just wont go away. i remember that there is a shader where in its settings i disabled something related to pbr and the sky would stop being black, as you can see the borders of things are pixelated and appear to show...

Axiom 'replace block' mode and Iris make the ground flicker/disapear
When using a combination of Axiom, and Iris (with a shader pack active, complemetary, BSL, bloop, any really), and enabling the "replace block" mode (keybind R), the ground will disapear and flicker when holding a translucent block (e.g., red stained glass). 1.21.4, Axiom 4.5.3, Iris 1.8.8.

Cannot handle shaders?
Hello, a friend of mine has an issues with his shaders.
Basically, he has a good pc, an rtx and such.. can play games like cyberpunk or baldur's gate on full resolution but he cannot handle shaders on minecraft, he uses iris shaders right now and it doesn't seem to work in any version, loader, modpack.. anyone can help?
His minecraft becomes reallyyyy glitchy and slow with shaders.
For myself, i have a different pc that is less good than his and can handle without problem..?...
What means this error:
CLOUDS: CLOUDS: Attribute iris_Position is bound to generic attribute 0, but gl_Vertex is also used.
