Not Parsing The New Block Model Format

[SpaceshipCaptain]

26.1-snapshot-6 and before defined the various stained glass models like this:

{
  "parent": "minecraft:block/cube_all",
  "textures": {
    "all": "minecraft:block/black_stained_glass"
  }
}

but as of 26.1-snapshot-7 and later the model now is defined like this:

{
  "parent": "minecraft:block/cube_all",
  "textures": {
    "all": {
      "force_translucent": true,
      "sprite": "minecraft:block/black_stained_glass"
    }
  }
}

The changelog:

Block Model Format

• Any block model can now support cutout or translucent (partially transparent pixels) textures
  • Whether a quad is rendered in the cutout or translucent render pass is determined by the contents of its assigned sprite
    • Any sprite with translucent (partially transparent) pixels will be assigned to the "translucent" pass
    • Any sprite with fully transparent pixels will be assigned to the "cutout" pass
    • All other sprites are assigned to the "solid" pass
  • Note: the assigned render pass also implies rendering order: all solid geometry is rendered before all cutout geometry, which is rendered before all translucent geometry
• The format of the textures map has been updated:
  • Non-string entries will now be rejected, instead of interpreted as strings
  • Alongside the previous inline sprite ID form, entries can now be defined as an object with fields:
    • sprite - the sprite ID
    • force_translucent - optional boolean, true if any geometry with this texture should be forced into the "translucent" pass
      • This is useful for example for blocks that don't have any translucent pixels, but use the mean mipmap strategy
      • Default: false

Right now deepslate is always expecting the texture property to be a string but now it can also be an object and the texture is in the sprite property of that object.

Possible fix on this branch
