example(like hypixel skyblock items):item a is the same item as item b, but item b has a different name(like runaan's bow)
BUMPITY BUMPITY BUMPITY BUMPITY BUMPITY BUMP
As of now, the only way to do this is with optifine. If you look for hypixel skyblock texture packs, they will all say optifine is required.
this doesn't help me at all because im talking bout bedrock edition
