I've been trying to get a multi textured block, an i ran into the problem not understanding what the "parent" in needed for.

when i use:

{

    "parent": "block/cube_all",

    "textures": {

        "all": "tm:blocks/grass_normal"

   

 

    }

}

 

everything works, but when i try to copy after vanilla grass:

 

{

    "parent": "block/grass",

    "textures": {

        "bottom": "blocks/dirt",

        "top": "tm:blocks/grass_normal",

        "side": "blocks/grass_side",

        "overlay": "blocks/grass_side_overlay"

    }

}

tm is my mod id.

use block/orientable (look furnace)

 

{
"parent": "block/orientable",
"textures": {
	"top": "blocks/_top",
	"front": "blocks/_front",
	"side": "blocks/_side"
}
}

But what if i need diferent top, sides and bottom?

 

could anyone show where all the vanilla parents are listed or how to create new ones, or even what are they???

Or just look into vanilla minecraft assets.

 

It's not like this thing will come to you on its own. It's really easy once you dig into it for few hours.

As to your question about any-side texture. You can do that. Read link (sounth, north, east, west, up, down).

 

As to question what is parent - it's literally what it sound like - you can inherit some other model (parent) and apply your own textures onto textures (#texture) deifned in parent model.

(Look wiki link: "Example: Any Block")
