Thanks for the very detailed tutorial! It was obviously a lot of work. And thanks for all the included pics, I had fun applying them all.
Here's some observations/questions, listed by tutorial section:
Introduction: Why do you say drawing simple round hills isn't easy? It's one of the easiest things to do in the editor, so I'm perplexed by that statement. In the paint tab/"Brush settings", check "Airbrush style", make the brush size maximum, "softness" approx 50% (middle of slider), and "flow" whatever you like (I prefer around 50%). If you paint on a reset (flat) terrain, you will get round hills without effort. If you don't, there's something wrong with your setup.
1.2 The slope that say would be "impossible" to do in the editor alone is actually fairly easy with the proper brush settings. To make sure I wasn't crazy, I did a successful test in less than 2 minutes. It had some irregularities, but those could've been worked out with a few more minutes work. If I wanted a PERFECTLY smooth slope, I agree a height map is a much easier way. But I'm concerned that if you think a slope is impossible to do in the editor, you haven't played with brush settings enough, or there's something wrong with your setup.
1.3 Regarding the black/white vs. shades of grey gradients: When Vue uses your bitmap, it "equalizes" the output. That's why the two different bitmaps result in the same slope. You should notice that the preview of the grey/grey gradient is already equalized, showing a full range of black to white. The reason the grey/grey terrain is bumpier is because you're using a smaller range of values (of the potential 256 values in an 8-bit greyscale) to represent the same altitude changes. The "banding" you mention is the result of using only 256 values, which really isn't enough. Someday we'll use 16-bit images (and have larger hard drives, hopefully) and that problem will go away. Until then, hit the "diffusive" erosion button tens of times to smooth those out or, as you say, use a texture that hides the banding. BTW, did you know "wedge-2" is sloping in the opposite direction from the others?
thanks again,
