getBuffer() allocates 1MB?

Is it just my misunderstanding? I'm referring to this: https://github.com/IrisShaders/Iris/blob/multiloader-new/common/src/main/java/net/irisshaders/batchedentityrendering/impl/SegmentedBufferBuilder.java#L36 Is there a workaround for this for mods with special entities / lots of particles that use getBuffer() frequently? Here's two spark logs - vanilla getBuffer() takes basically no time, so it is kind of unexpected that this method gets such a huge overhead....

Item not displayed

When I dig out blocks like sugarcane and water lilies, they are transparent. I'm not sure if it's caused by other mods, but after I disabled iris, it displayed normally

Iris reordering draw calls for GeckoLib4 render layers [1.21.1]

Iris seems to be reorganizing draw calls for GeckoLib4 render layers. I'm drawing using a GeoEntityRenderer that is sensitive to the order in which the draw calls occur, and when Iris is installed the order gets messed up. Notably this doesn't happen with Sodium installed but not Iris. I have some RenderDoc captures, one with the issue occuring (with Iris installed) and one without the issue occuring (with just Sodium installed). Code snippet with the intended order (glow, claws, armor, item) but in the screenshot with the issue, the armor ends up rendering before the glow layer, causing the glow layer to overlay on top of the armor....

Lag whenever I open any form of GUI when i have shaders enabled

It runs fine when Im playing normally. But when I open my inventory or chest, I drop to like 5 fps. Interestingly, the F3 menu doesn't reflect that frame drop.

WHEN forge, an very old question

I see iris as an amazing tool for shaders, but, come on, forge would be dope, and 1.20.1? Epic

Sun shines through DH LOD's with shaders.

What could be the root cause of this? Using Bliss shader. I'm assuming this is happening due to light rays not taking into account LOD's that are facing away from you, for optimization; normally blocks or textures of geometry are not rendered when you cant see them. So this is causing the light to be calculated through the LOD's / Block faces that are invisible/without textures. and the sun shafts just go straight through. So is this something that shader devs can fix?

Minecraft - 1.21.4 - Reference maps are unable to be read

Hello, I'm working on making a small modpack for myself and trying to have as few warning / errors as possible, are these warnings something to be concerned with?

Solution:

as far as I know those warnings are not important and don't indicate a major problem. Warnings can usually be ignored unless you experience issues

Crashing when joining servers

I installed iris but everytime i join a singleplayer world or server it crashes my game, with the only way to not crash is by removing iris from my mods folder, is there any way to fix this?

(Mod) Is it possible to prevent shaderpack affecting OpenGL graphics?

I hope it's okay to post this here since it is related to Iris shaders in some way and question is more for developers or maintainers (edit: also asked in https://discord.com/channels/507304429255393322/807617488313516032/1322573345727709295) I'm developing a mod which draws some opengl graphics but let's just take these arrow trails for example. I noticed that certain shaders influence the opengl triangles and quads, some make them glow, some lose transparency, some don't render them at all, all sorts of weirdnesses. From a mod's perspective, is it possible to disable currently enabled shader to affect my custom shapes?...

crashing on world generation (1.21.1, neoforge)

hi! ive been trying to run iris + sodium with neoforge except when the world finishes generating my game crashes. the world generates fine when i only have sodium without iris but adding it crashes the game with the error message "org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered". added the mod compatibility tag because i know it might be an issue with that but im not sure... -_-

Solution:

update iris

Floating chests

For some reason, when shaders are enabled, chests float around when they should be in the hand. A video may be sent soon if I can get it under 10mb
