it is as the title says

I'm trying to create a mod for fun and keep running into this one issue

I have a helmet i want as the first armor piece of many, but i can't get it to be the model when it is worn by the player or the armor stand

everything i have tried so far kept ending with it being a purple block when worn

i even tried to just use the default model for netherite helmet and the same thing happens

am i doing something wrong?

i have screeenshots of how it looks

 

The magenta is a sign of a missing texture.

If you're doing a custom texture you need to store the png as "...assets/[modid]/textures/models/armor/[armor_name]_layer_1" or as "...assets/[modid]/textures/models/armor/[armor_name]_layer_2".

"...layer_1"'s for helmet/chestplate/boots, "...layer_2"'s for leggings.

Then you just need to return "[modid]:[armor_name]" in the .getName() method of the ArmorMaterial provided to the ArmorItem as argument to it's constructor. If you're using a texture in minecraft's resource pack you can just omit the modid.

If you're trying to make a custom armor model as well, I don't know anything about that part off the top of my head.
