[Feature] Support for custom mob models

[DedMaxim]

If a resource pack that changes mob models is installed (Mobs Refreshed for example), mob heads break because they use custom texture on vanilla model

There are 3 possible solutions I can suggest:

1. Add support for custom models provided by CEM feature from EMF/OptiFine. I'm not sure how difficult it would be though.
2. Ship custom head models and custom textures for those models inside the mod. This way resource packs won't affect models from the mod.
3. Force models from the mod to use textures from Minecraft, if it's possible to do while a resource pack is overriding that texture

3. would be the only real solution here.

Are the textures from Minecraft still there, though? I assume they add a custom model, but then override the vanilla texture?

[DedMaxim]

Yes, they do override it. That's why I'm not sure it's possible to do. Technically, the file itself is still there, in the jar file, but in a running game it's overwritten by a resource pack. I just don't know if it's possible to make Minecraft still load original textures and then point to them

This approach is used pretty much by all resource packs though. I guess it's done so that original textures don't waste RAM. With FreshAnimations, for example, heads don't have eyes because FreshAnimations has eyes placed separately

Had this happen with a villager replacing mod. Ended up with resource pack's textures trying to map onto a vanilla model, and villagers had proper replaced one. Was done with this mod https://modrinth.com/mod/entity-model-features

@DedMaxim I don't see how minecraft jar is at all relevant here...? As for the proposed solution, trying to sidestep the resource/registry system sounds like a bad idea ^^" The vanilla texture just wouldn't be available as long as the resource pack is loaded.

Anyway pretty sure the mod does some custom model shenanigans, and like a normal texture pack also replaces the texture resource.

I understand that it's probably a bad idea but that's still a theoretical solution to this problem! I'm just trying to make suggestions how it possibly can be fixed. Maybe there's an easy answer that I just don't see
