Halo,thanks so much to both of you guys!
I'm already re-exporting my collada meshes from Blender as multiple and it works just fine. I suspected it had something to do with Child object node but had no idea how to use it. I will also check out Karl Henkel's custom Parabox nodes, sounds interesting! I checked the Arrange 3D Objects in Grid...that would be like QC's Iterator more or less right?
Well,thanks again for your input!
