Mesh.CombineMeshes

function CombineMeshes (combine : CombineInstance[], mergeSubMeshes : boolean = true, useMatrices : boolean = true) : void

Description

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.
