| combine | Descriptions of the Meshes to combine. |
| mergeSubMeshes | Defines whether Meshes should be combined into a single sub-Mesh. |
| useMatrices | Defines whether the transforms supplied in the CombineInstance array should be used or ignored. |
Combines several Meshes into this Mesh.
Combining Meshes is useful for performance optimization.
If mergeSubMeshes is true, all the Meshes are combined to a single sub-Mesh. Otherwise, each Mesh
goes into a different sub-Mesh. If all Meshes share the same Material, set this to true.
If useMatrices is true, the transform matrices in CombineInstance structs are used. Otherwise, they are ignored.
Set hasLightmapData to true to transform the input Mesh lightmap UV data by the lightmap scale offset data in CombineInstance structs. The Meshes must share the same lightmap texture.
