[discord suggestion] A cleaner web experience for this forum

Hey! I saw this forum uses AnswerOverflow to sync Discord threads to the web. I’m building Paladin, a smoother, cleaner alternative that makes Discord forums easier to browse on the web. It’s free to use and can run alongside AnswerOverflow, so you don’t have to switch anything to try it out. If it’s helpful, I can spin up a version of Paladin on your forum so you can see how it looks for your community. Is there anything about your current setup you’d like improved? I’d love to see if Paladin can help. 😀 Example Paladin preview attached...

My game crashed every time I opend my Inventory, so I tracked it down to Iris (1.9.1) on the MC version 1.21.7. When I remove the mod, my inventory is fine, but with it, it crashes

Iris wont load Shaders

Hello, im on minecraft version 1.21.1 using iris-neoforge-1.8.12+mc1.21.1.jar and every time i try to load a shader i get the following error code: shadow_solid: java.lang.IllegalArgumentException. Anyone have any idea what this could be? Thanks!...

Solution:

Seems like you're running a beta version of Iris? If you got it somewhere here, see if downloading and using the one on Modrinth changes anything.

Immersive portals plus Iris troubleshooting

Ello, I'm trying to use this mod fork of immersive portals thats claims to "Fixes multiple bugs and crashes with immersive portals with connector, iris, and sodium (works with embeddium and oculus too 😄 ) compat with complementary shaders with euphoria patches :D" https://modrinth.com/mod/immersive-portals-continued/changelog The issue I'm facing, the oldest version of the mod is 1.20.1 which is the version I wish to use, but the versions of iris and sodium it works with seem to only be for 1.21+ So I'm unsure how to proceed?...

Hey! Game crashes upon loading up world

When i load my world my game crashes. If i turn shaders off and load in, everything is fine! I can even turn shaders back on AFTER joining the world with them off. But after a few game restarts the crashes happen again. YES I am aware i have sinytra connector in this pack. But i have removed connector and all fabric mods and i STILL get this issue! Thank you for any help! java.lang.NoClassDefFoundError: Could not initialize class net.irisshaders.iris.pathways.FullScreenQuadRenderer...

Solution:

seems to be caused by ProbeJS
