API function: algo.combineMeshes Use this feature along with scene.mergePartOccurrences to combine part occurrences and their assigned materials. The result is a similar looking model, but the number of draw calls is reduced.
These operations are performed:
  • Geometries are merged, but they aren't modified.
  • Texture coordinates are combined and repacked into a single atlas.
  • Material information is transferred to a single set of textures. This set is used by a single material that's applied to the combined mesh.

  • Roughness
  • Specular
  • Metallic
  • Ambient occlusion
The output material contains the packed textures atlas:
