IRIS NOT WORKING PROPERLY

OK, so i use lunar, on 1.21.4 i had no issues running any shaders at all, hardware is not the issue in this case and i know this becuase it worked fine previously.

[1.21.5] Position Color support not included?

I was unable to submit this to Github so trying here: I was previously using a rendering API for one of my mods that used the old PositionColor program. When they updated their API to 1.21.5, they use a new RenderLayer of the RenderPipelines.POSITION_COLOR_SNIPPET. However, from what I can tell, Iris does not have this implemented into the pipeline. I could be misunderstanding what is going on, but when cloning the repo POSITION_COLOR_SNIPPET does not even exist within the RenderPipelines that was generated/included....

iris bug 1.21.5

Volumetric lighting and TAA is broken in all shaders. Volumetric lighting does not disappear after being rendered (does not disappear after looking away from source), possibly due to TAA?. TAA is broken as it still keeps all temporal pixel data starting from when the shader was enabled instead of removing them, leading to blur and smudging in motion and weird artifacts....

OpenGL 3.2 how to fix crash ?

Hello, I have a crash that occurs when I try to run Oculus (the latest version). With version 1.6.13, I had no problems, but it seems that now you no longer support OpenGL 3.2. How can I fix this problem and be able to play with shaders (as before)? Oculus is the unofficial version of Iris (for Forge), but works in the same principle. The author told us that we should move towards Iris support....

Iris doesnt want to load any shader

idk why, but it outputs an error into the chat : net.minecraft.server.ChainedJsonException: Invalid shaders/core/basic.json: Non [a-z0-9/._-] character in path of location: minecraft:basic_tessControl.tcs my modlist here: https://gnomebot.dev/paste/mclogs/XNNK918...

Using iris causes flickering

When i use iris all entities start flickering. Tried different settings (on sodium and Iris), removing all other mods yet no difference. Using sodium itself with other mods is fine but only putting in Iris causes the flickering.

Optifine skybox using iris

Iris talks about optifine skyboxes and their ability to use them, how exactly do you do that? i have iris and sodium installed have the skybox in resource pack and i dont know exactly where the compatability comes in

shaderpack failed to load

hey there, i'm using a pretty hefty amount of mods, including distant horizons with photon shaders which are advertized as compatible with distant horizons. i'm using the physics mod as well which can cause some issues with shaders but i've been able to run this mod combination previously without problem. currently about 9/10 times when i open the game i get the message "the shaderpack failed to load! please report the error to the developper" the info included in the message is the following: prepare.vsh: prepare.vsh: 0:38(63): error: `base_color' undeclared 0:38(63): error: type mismatch 0:38(38): error: no function with name 'linear_step' 0:38(34): error: no function with name 'sqr'...
Solution:
update: i just downloaded the latest photon commit from the github page and it works now!
