Block with generated texture

[lupuchard]

Hi, I want to create a simple block where the textures are generated upon loading by modifying a vanilla texture. I've created a ICustomModelLoader and can load the base textures from the resource manager, but I'm not sure what the best way to do the remaining steps is? I suppose I could create a custom IModel and IBakedModel but that seems like overkill for what should be fairly simple. The VanillaModelWrapper is private and none of the other IModels are well documented as to their purpose. What's the expected way to do something like this?

Modify how? Does an overlay texture not work?

I wanted to do something similar to DenseOres (https://minecraft.curseforge.com/projects/dense-ores) where they automatically expand the ore textures, but I've looked at the source and am having a hard time following their loading process (they are not using an ICustomModelLoader).

They do it with a TextureAtlasSprite

I don't recommend doing it this way.

1) create a block model, like this: https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/src/main/resources/assets/harderores/models/block/hardore.json

2) create a blockstate file, like this: https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/src/main/resources/assets/harderores/blockstates/ore_hardiron.json

Note the #overlay texture. That's your ore pixels portion (my ores are metadata => number of nuggets, not metadata => ore type).

3) Then create overlay textures, where alpha shows the texture of the base material (my ores actually operate in reverse, due to how I use metadata). e.g. https://github.com/Draco18s/ReasonableRealism/blob/1.12.1/src/main/resources/assets/harderores/textures/blocks/ore/overlay_15.png
