Hi! I've been exploring the new 1.21.4 resource pack features, and it seems like it should be possible to create custom armor or elytra textures using custom model data. However, I've tried setting it up and can't seem to get it to work.
Just to clarify, I don't want to use any mods or custom models; I'm only focusing on textures.
Does anyone know how to make this work, or can confirm if it’s not possible? Thanks in advance!
