OK I haven't used TG2 in a couple of weeks but I want to give terrain another go, I've never really put much effort into terrain so it'd be great to do some cool things beyond the generated power fractals. What I really want to do is create a scene like Bella Coola but with mountain ranges like this

Edit: ooh ooh also, has anyone worked out a good way of doing waterfalls yet? I want to have rapid flowing rivers down the crevices like in the LOTR movies.
can't see it its blocking the link.
How about this? ;D I'd imagine this could be done with displacement offset but I'm not sure.

Try image masking a cloud that's got serious stretching in the fractal's Y?
It looks to me that is a thin flow erosion with deep cuts. Terragen 2 can not do these effects that i am aware of as currently the erosion model to me seems like a simplified classic erosion model with softer cuts, could be off there but it looks like this to me. For that type of terrain feature best to use World Machine with a deep cut flow and Geocontrol but both softwares should get you the look you are after for mountains like that.

Can't offer any help, but when I saw that picture I thought "Hey, that looks like NZ" and then I scrolled down and saw the caption :-).

The Alpine Fractal shader in TG2 might also get you similar results with some tweaking. Perhaps combine several Alpine Fractals or Power Fractals...

Yeah I've been trying the alpine fractal, although I'm not looking forward to masking the foreground to flatten it. Could I tweak it so that the mountains are insanely close together and then tweak the altitude of the peaks with the get altitude function and have a little mathematical formulae to have a min and max altitude and then add some power fractals and displacement to get those deep crevices?

Me too! :)

Well I haven't had much luck so far. The flow graph format of world machine 2 trial is a bit overwhelming for me to get into. And I don't really want to buy a license if I can't use it properly. Geocontrol seems a lot better for me although a lot of it is locked in the trial. No brush settings for starters. Don't know if I want to pay near enough £100 for a terrain tool.
The art of zen.... think about what you are trying to achieve and then translate it into TG terms
Try playing with the deposition settings in the alpine fractal. You want the erosion to go all the way down the mountain - reduce early deposition and early deposition rate ... but you want some flatter areas in the valleys - increase late deposition.
Wow. that works really well. I had no idea what they were for. We should really get that Wiki idea back, have articles on each option group (e.g. deposition). I'll have a play around with these
