Mesh.subMeshCount

説明

The number of sub-meshes inside the Mesh object.

Each sub-mesh corresponds to a Material in a Renderer, such as MeshRenderer or SkinnedMeshRenderer. A sub-mesh consists of a list of triangles, which refer to a set of vertices. Vertices can be shared between multiple sub-meshes.

        Debug.Log("Submeshes: " + mesh.subMeshCount);
    }
