[SOLVED] [1.12.2] Block model with random textures on random sides?

[Evi1Casul]

UPD: SOLVED

 

Hi. I've been trying to create a block attaching to adjacent blocks on 6 sides (kinda vines) with random textures. And the problem is... Wait, a quick maths: 11 vine models for 5 sides + additional bottom side = 23 models, and with 6 different textures it reaches 138 (!)  Is it possible to randomize textures on different sides, because 23 * 6^6 models is a little too much?

Example of a model x_1d_1 (1 side + bottom, texture 1):

{
	"ambientocclusion": false,
    "textures": {
        "tex": "modid:blocks/tex_1"
    },
    "elements": [
        {   "from": [ 0, 0.8, 0 ],
            "to": [ 16, 0.8, 16 ],
            "shade": false,
            "faces": {
                "down":  { "uv": [ 0, 0, 16, 16 ], "texture": "#tex_1", "tintindex": 0 },
                "up":    { "uv": [ 0, 0, 16, 16 ], "texture": "#tex_1", "tintindex": 0 }
            }
        },
        {   "from": [ 0, 0, 15.2 ],
            "to": [ 16, 16, 15.2 ],
            "shade": false,
            "faces": {
                "north": { "uv": [ 0, 0, 16, 16 ], "texture": "#tex_1", "tintindex": 0 },
                "south": { "uv": [ 0, 0, 16, 16 ], "texture": "#tex_1", "tintindex": 0 }
            }
        }
    ]
}

 

First texture is used on each face here and model x_1d_2 differs only in texture number.

So can I add all the six textures to the model and randomize it? Thanks in advance.

You can specify multiple textures and Minecraft will grab them at random based on the block's position automatically.

I don't remember exactly how to do it though.

I think I may have found a solution, and this can be done with extended blockstates, but I have to check it.

I tried to use multimodel and submodels system, but it still generates all the possible sets of variants (as I said, with 6 different textures on 6 sides it loads over a million models). Is it possible to override the block renderer so it can pick a random texture dynamically? I found it too dfficult to create an advanced model (using a custom model loader, etc.), it seems there's not even a premde IModel class for block (only ItemBlock and private vanilla wrapper).

This is how vanilla handles it:

{
    "variants": {
        "": [
            { "model": "block/stone" },
            { "model": "block/stone_mirrored" },
            { "model": "block/stone", "y": 180 },
            { "model": "block/stone_mirrored", "y": 180 }
        ]
    }
}

Notice that each variant is an array. Every blockpos generates a random result from this array.

 

I'm also not sure how you got "over a million variants." 6 sides ^ 6 textures is only 46656.

Yes, I also used this in my blockstate, like this:

"north": {
  "true": {
    "submodel": {
	  "face0": [
		{ "model": "modid:model_0" },
		{ "model": "modid:model_1" },
		{ "model": "modid:model_2" },
		{ "model": "modid:model_3" },
		{ "model": "modid:model_4" },
		{ "model": "modid:model_5" }
	  ]
	}
  },
  "false": { }
}

Because the block can attach to each side (like vine, but with an additional bottom side), so it's 2^6 * 6^6 = 2985984 (3M) variants (if my calculations are correct).

 

P.S. 46k models is a lot too, I think. I can dublicate these 64 (2^6) variants and randomize textures automatically with IO and string replacement to get like few hundred variants, so every texture would be used, and that will give some feel of randomess, but I still want to find a way to do this with all the possible combinations dynamically.

I could have sworn there was a better way of doing this.
