It would be great if renderworks textures allowed you to use Tiles in addition to Hatches for their Surface Hatch, mainly because it's 1000X easier to create something from scratch as a Tile compared to a Hatch.   If there's a technical reason why Tiles can't be Surface Hatches, then attention needs to be given to the Hatch Editor to make it more user-friendly. (This is true either way, I suppose).
