Combining Textures During Runtime

[jgrimes900]

I have no clue how to do this. What I need is some way to add transparent textures together as sort of layers. Maybe use some sort of NBT tag system, I don't know. I feel like this is really specific and I don't know how to not make it sound like I want someone to code for me.

You can create models with multiple layers just fine:

https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/src/main/resources/assets/harderores/models/block/hardore.json

It is also possible to read two (or more) textures off the disk and combine them during the texture sheet stitching process, but it's not documented and can be difficult to do right (and if it crashes the game, its very hard to diagnose).

 

If you want to do items with layers, based on NBT, that's doable too. You need to define a Custom Mesh Definition:

And register it:
