The 3d armor feature is great but it's confusing
Ex. If you are making a 3d armor RP, you will be confused with "modname_armor..."

Describe the solution you'd like
Instead of making the 3d armor to be
zombie_armor_... Or smth
You should make it easier
Like make it
diamond_armor... Smth
iron_armor.... smth
And for cit
wizard_armor...smth
enchanter_armor...smth.

Does OptiFine do this
No optifine refuse to add this

As great as this is it would be fairly difficult, I can think of a few ideas but it's not a priority for now

This is also fundamentally different from the vanilla model behaviour

Hm
You can take your time as much as you want

But if people want to make a big pack with 3d armor and cit of that armor
Yeah that's gonna push the performance really hard

Since the 3d armor feature you can
Just add another set named
Player_diamond_armor_layer_1.jem
Or
smth
And for the mobs you can do the same
Zombie_iron_armor_layer_1.jem
Or
Smth
Instead of redoing the whole feature
Add a player armor model
And separate armor set with a model
If that makes sense

outer_armor.jem and inner_armor.jem were added as fallback armor models last update
