Hello,
I am using 1.19.2 version of MC with Rubidium.
In Chocolate minecraft modpack the connected textures are not working.

Is it possible to fix it somehow or is there maybe an error on my side.

Thanks

Please fill in the template, it is there for a reason.
Nothing I can do about issues with Rubidium as it is likely caused by them. I would suggest using Embeddium instead.
