when any furnace is used the texture messes up

im using fabric 1.18.1 sodium and iris when i disabled the blending resource pack it was still there

What? never seen anything like this xD

I see you are using some other texture-blending pack. Which one is it exactly? Are you using any mods or shaders?

Also, what game-version are you on?

I am having the same problem. I believe it has more to do with sodium or iris than the texture pack. It could also be indium, as that is required for some types of 3d block rendering in texture packs.

Sorry for being gone for a while but here i am lol.

So i did some more testing and research about this and I'm afraid to say, that i can't fix this.

Looks like this is an issue with Sodium other people have already found:
CaffeineMC/sodium#226

I'll leave this issue open for now.

Update: according to this pull request on the sodium-repo, it has been fixed an will probably be in one of the next sodium updates.

CaffeineMC/sodium#1375

Update: This seems to be fixed with Sodium 4.6!
