🐟 需要设置face.manulUV = true

        public static void Set01UV(this ProBuilderMesh mesh){foreach (var face in mesh.faces){face.manualUV = true;//设置为手动uv}var vertices = mesh.GetVertices().Select(v => v.position).ToArray();var uvs = vertices.GetPolyMesh01UVsXZ(); //自定义uvmesh.SetUVs(0,uvs.Select(uv=>new Vector4(uv.x,uv.y,0,0)).ToList());mesh.Refresh(mask: RefreshMask.UV);//刷新uv}
