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.
