I've seen that Chaos Cosmos fabric materials come with an individual node for each map. This is not practical when it comes to editing Randomizer and Triplanar nodes. Since we have the possibility to use Multiple Outputs, it would be nice that all maps are connected to a single randomizer node and then a single triplanar node. So the editing will be faster and simpler.
This will be out in Corona 14, and is already available in the Preview build (see https://forum.corona-renderer.com/index.php?topic=45313.msg235216#msg235216 )
