Hello,

How can I make a multilayer block model?

With that I mean I specify the texture of layer 1 and layer 2 and layer 2 gets rendered on top of layer 1.

I've tried:

{
	"parent": "block/cube_all",
	"textures": {
		"all": "blocks/stone",
		"overlay": "dgm:blocks/cheese_ore"
	},
	"elements": [
		{
			"from": [ 0, 0, 0 ],
			"to": [ 16, 16, 16 ],
			"faces": {
				"down":  { "texture": "#overlay", "cullface": "down" },
				"up":    { "texture": "#overlay", "cullface": "up" },
				"north": { "texture": "#overlay", "cullface": "north" },
				"south": { "texture": "#overlay", "cullface": "south" },
				"west":  { "texture": "#overlay", "cullface": "west" },
				"east":  { "texture": "#overlay", "cullface": "east" }
			}
		}
	]
}

But that only renders the overlay and the transparency in it white.

Then I tried making the block opaque etc. and that ended up making the transparency transparent without the other layer:

public class CheeseOre extends Block {
	public CheeseOre(Material materialIn) {
		super(materialIn);
	}

	@Override
	@SideOnly(Side.CLIENT)
	public BlockRenderLayer getBlockLayer() {
		return BlockRenderLayer.CUTOUT;
	}

	@Override
	public boolean isFullCube(IBlockState state) {
		return false;
	}

	@Override
	public boolean isOpaqueCube(IBlockState state) {
		return false;
	}
}

So how can I do it?

Add more elements with a different texture reference.

That's basically what I did, as you can see I 'extended' block/cube_all and specified the stone texture to it.

No, you overwrote block/cube_all's elements. You didn't add, you replaced.

Oh sorry, didn't know I did, how can I add instead of replace?

You can't. The "elements" tag is specifically a replacement. Actually all named tags are replacements. Its just that in some cases (like the "display" tag on items*) that things aren't replaced, and it has to do with how the files are deserialized.

 

You MUST add all 6 sides to your model twice, each with a different texture. There is no way around this.

 

*This reason this is true is because "display" is an object. Each subtag present replaces the parent's original. "elements" is a list and there's no way to know that the element list you've supplied should add or replace the parent's list, so the default action is replace (if the default was add there would be no ability to replace).

Okay, thanks

Now, the purple/black texture appears. My new block model:

{
	"parent": "block/block",
	"textures": {
		"block": "blocks/stone",
		"ore": "dgm:blocks/cheese_ore",
		"particle": "blocks/stone"
	},
	"elements": [
		{
			"from": [ 0, 0, 0 ],
			"to": [ 16, 16, 16 ],
			"faces": {
				"down":  { "texture": "#block", "cullface": "down" },
				"up":    { "texture": "#block", "cullface": "up" },
				"north": { "texture": "#block", "cullface": "north" },
				"south": { "texture": "#block", "cullface": "south" },
				"west":  { "texture": "#block", "cullface": "west" },
				"east":  { "texture": "#block", "cullface": "east" }
			}
		},
		{
			"from": [ 0, 0, 0 ],
			"to": [ 16, 16, 16 ],
			"faces": {
				"down":  { "texture": "#overlay", "cullface": "down" },
				"up":    { "texture": "#overlay", "cullface": "up" },
				"north": { "texture": "#overlay", "cullface": "north" },
				"south": { "texture": "#overlay", "cullface": "south" },
				"west":  { "texture": "#overlay", "cullface": "west" },
				"east":  { "texture": "#overlay", "cullface": "east" }
			}
		}
	]
}

The console and client log give no errors.

Couple things:

1) Your overlay texture is #overlay, you didn't specify a resource location (this is likely the problem).

2) You haven't specified any UV coordinates. You probably don't need them, but it's good form to have them.

Ah yeah, forgot to change #overlay to #ore. Now it works, thanks!
