That video is very cool. I was having a few ideas on how I could use it in my workfow. I'm using Wilbur
at the moment- that's very good at generating incised channels in the terrain, but it's not as complete a
solution as GeoControl. Wilbur does support larger terrains though, and if you're using large terrains
you need your rivers as relatively narrow as you can get them. I work to a river map pre-drawn, so
I perhaps have a slihgjtly different set of consideration to you Mocha-don't know.
I tested both GeoControl2 and World Machine2 when they were in development, the spline tools in Pro 2 are
extremely good too, as you said DandelO. I think GeoControl has better river tools though, but World Machine has
other advantages- it can do massive terrains.
For me, I'm still really at the experimenting stage with preserving, creating rivers in my terrains at the moment.
The video linked illustrates the basic problem, that if you want natural looking "tree-like" river systems,
you have to set up the terrain to encourage their formation. That's basically what I do in my terrain model, but it's a very time consuming process. I learned a few things
from watching it though.
I've also not really considered very much the solutions for rivers and lakes in the renderers, but I'll be
toning down the incision depth next time in Wilbur because you can create that in Terragen via masks and
displacement.
The voronoi patterns sounds promising. I was looking at a World Machine macro created by Nikita using voronoi noise to create rock
structers- fractured patterns. They were pretty convincing too and I saw the basis for good
river patterns in them. I think I came across that thread in my searches recently. Was this it?
