Thanks again, reading this is very encouraging for me. And it's true - Terragen 2 has become a very complex application, compared to Terragen 0.9, which has attracted countless hobby artists. In my opinion, a big part of TG0.9's success has been the simplicity of use. Most of the maths that worked behind the scenes have been hidden from the user. Still it was complicated enough to have a considerable learning curve. Just look at all the tutorials that are everywhere around the web!
Now, in order to make TG2 more accessible not only to beginners, but also to less maths savvy individuals, I really believe that the "presets" that I make can provide good value to the aforementioned group of people. Some will study and learn the presets, and eventually make their own skies, terrains, function etc.., while others will be content assembling nice images using various pre-configured aspects of TG2. All of that is a viable approach for art.
I am looking forward to the day when TG2(3) has a facility to create macros of some sort, so that e.g. a given set of cloud layers can be packages into just one node with just one custom dialog, so that these presets become very easy to use. I will be the first one to create some of those custom macros :-)
Best regards,
Frank
