Advanced Block Types

Cuboid Variants

• cuboid: Basic custom-shaped block

• cuboid-16way: 16-direction connecting
• cuboid-nsew-stack: Stackable connecting blocks

These types share similar properties but have different connection behaviors.

Basic cuboid configuration:

{
  "blockType": "cuboid",
  "textures": ["texture1", "texture2"],
  "cuboids": [
    {
      "xMin": 0,
      "xMax": 1,
      "yMin": 0,
      "yMax": 1,
      "zMin": 0,
      "zMax": 1,
      "sideTextures": [0, 0, 0, 0, 0, 0]
    }
  ]
}

All cuboid types support:

• Multiple cuboid shapes
• Custom textures per face
• State-based variations
• Random rotation
• Color multiplication
• Custom models
