This is one of the reasons I was not too enthusiastic about the technique in TG2. It's best to have something a bit rougher and less angular. The steep steps basis function in Mojoworld allows you to create grids and have smooth corners. I did use other techniques but found it quite difficult to get something interesting when it came to surfacing. Mojo has problems with surfacing on very steep slopes. I think TG2 may be different in this respect. I don't know yet how we could create a more rounded appearance. This would facilitate using all TG2s more natural surfacing better but who knows yet, a geometric style cybercity may well be fine. Sadly, I can't get heavily into this. I have one render which is going on Renderosity tomorrow then I have to stop for a while to sort out the horrendous backlog of other stuff I have to do. I also want to do some more general work on building up more complex surfaces for more interest in one planet. There are no end of avenues to explore. Impossible to do it all.
