Mesh.CombineMeshes

Описание

Combines several meshes into this mesh.

Combining meshes is useful for performance optimization. If mergeSubMeshes is true, all the meshes will be combined to a single submesh. Otherwise each mesh will go into a different submesh. If all meshes share the same material, set this to true. If useMatrices is false, the transform matrices in CombineInstance structs will be ignored.
