Properties

Property	Type	Description
formats	textureSetDefinitionFormat[]	List of formats that are available for this texture set.
atlas	boolean	Set to true if this texture is a texture atlas. It is expected that geometries that use this texture have uv regions to specify the subtexture in the atlas.

Note: properties in bold are required

Examples

Example: Texture set definition (desktop: jpg+dds)

For a mesh with material.resource=888, JPEG will be at /layers/0/nodes/888/textures/0 and DDS at /layers/0/nodes/888/textures/0_0_1

 {
  "formats": [
    {
      "name": "0",
      "format": "jpg"
    },
    {
      "name": "0_0_1",
      "format": "dds"
    }
  ]
} 

Example: Texture set definition with ETC2 compresses image (Mobile: jpg+ktx-etc2)

JPEG texture will be at /layers/0/nodes/{nodes[i].material.resource}/textures/0. Same texture in KTX format will be at /layers/0/nodes/{nodes[i].material.resource}/textures/0_0_2

 {
  "formats": [
    {
      "name": "0",
      "format": "jpg"
    },
    {
      "name": "0_0_2",
      "format": "ktx-etc2"
    }
  ]
} 

Example: Texture set definition with atlas

 {
  "formats": [
    {
      "name": "0",
      "format": "jpg"
    },
    {
      "name": "0_0_1",
      "format": "dds"
    },
    {
      "name": "0_0_2",
      "format": "ktx-etc2"
    }
  ],
  "atlas": true
}
