Is there any docs with examples which can explain the density fractal settings?
For the first thing i would like to understand what is feature scale, lead-in scale, smallest scale things are and what are all the "tweak noise" panel settings for? And how those settings relate each other?
Density Fractal is just a specialized version of the Power Fractal with different settings. Power Fractal docs can be found in the Node Reference (still in progress, but a good deal of info is already there): http://planetside.co.uk/wiki/index.php?title=Power_Fractal_Shader_v3

Thanks, It's good to have some basic info. I am not sure although I still feel those settings intuitively without example pictures.
What is a quickest way for an instant preview of the noise settings changing? I know, there is a small preview window but it works not very responsive. Maybe with a main render?
Is there any 3d party noise generators that would work with Terragen?
If you have the animation version, you could setup a short animation of each setting acting on its own, and render out a series of frames at low resolution. This should go fairly quickly if you do it on a basic terrain with no surfacing, which will still show you the effect well enough.
There are no 3rd party noise generators that work with Terragen.

You can zoom in in the preview window, and see quite precisely what happens if you change settings. If you have some color checked. I use that all the time.
The preview window looks like working of one cpu core probably and take some time before it shows a changing precisely. The main render probably would do it quicker on a kind of single square plane if stripped of everything . I would like to make a test scene for that purpose and curious how to do it right. Guess I don't need the lighting, planet, atmosphere , GI, AA but still have to keep detail slider high. A kind of special tgd file for noise setting only.
I believe I can't do animation in my version but still hope to use the same idea of making a set of preview pictures.
