I'm going to bitch... so sorry up front for this. <Begin Rant> Can't you developers make this program easy to understand? Or barring that. update the documentation with better interface instructions <End Rant>
Frank, I took a look at the default preset and while it produces wonderful results, I thought it would have been an excellent "entry" to TG2 for newcomers. So, not being a new-comer I start digging to see if I can understand it. The first thing that I come across that catches my curiosity is the "connect to compute terrain" node. I see that it has really low values and I can't understand how such low values could result in the landscape that I see. A little bit of research and I see that I have to right click on the "fractal terrain" group, and then I see how the three inside nodes Base Perlin, Medium size details, small size details.
Gripes:
1) finding them - who would have thought to right click on the group.
2) I see no indication of how they tie into the rest of the node network. Connect to Compute Terrain doesn't document being tied to them, and the hidden three gems show no indication of how they are tied to the node network - except by their being in the "add Terrain" panel.
Sorry - I'm probably going to find out that this is clearly documented and that I just failed to look and see it. If given a choice of styles, I prefer the what DandelO did with his boss grass shading node, that had internal components. With that concept, I have a sense of placement and sequence. Again, I am probably missing something very basic - and it is me.
On another note, I appreciate very much the work that everyone is doing to make TG2 a success - we are the ones that benefit from that!!
