Question
Is there a zip file for the connected glass? I only know how to add zip files to resource packs. I'm unfamiliar with jar files, and I don't want to add mods to the CurseForge app. I prefer to add mods to the Minecraft app itself.

If you don't have the zip file for the connected glass, can you teach me how to convert jar files to zip files so I can use the mod on the resource pack? I'm using Optifine, by the way, so I want to make sure doing this doesn't cause my game to crash.

Connected Glass is a mod, not a resource pack. You cannot add new blocks and items with a resource pack so there is no way to convert it to a resource pack.

So I have to use the CurseForge app. Okay
