Indium conflicts with rexxstone's resource pack when modifying it to use clean redstone, the redstone beceomes big red and black square. Also creates conflicts with other blockstate altering textures.

Closing (unable to reproduce issue)

Does this occur with only Sodium, no Indium? Please provide the resource pack that you used, and what it should look like, so I can test it myself.

Disabing indium fixes the issue. I am using rexxstones resource pack

Default values of the pack work with indium, however when changing redstone texture using this guide:https://www.youtube.com/watch?v=mHzThetR9l0
Indium breaks the clean redstone.

This appears to work fine for me. Have you set up the pack correctly? What versions of Indium and other mods are you using?

I should probably change version, just realised I was using alpha. Will update you.

What version of indium are you using? There is only an alpha build for indium 1.18. Do I have to build it from source?

I'm using the released alpha versions of Sodium and Indium for 1.18; 0.4.0-alpha5 and 1.0.2-alpha1 respectively.

Thanks for your help, I was using the build produced from running the gradlew.bat

Did you manage to fix the issue? or does it still occur using the released versions?
