that looks superb in df- imagine what can be done with these maps...!

I opened the last one up in Wilbur too. Everything seemed fine. I think this is almost certainly me misunderstanding the nodes in TG. I'm converting the heightmap to an image mask in Wilbur. I think I need both a heightmap and an image mask to control the surface extents...that's just one thing I'm not sure about. I think it's time to have a good chat on the TG boards about this.
The excess water can be removed no probs I think.
