Heya

I have only JUST started on my first height and terrain mask map. I ask nicely - can you use the 'WaterMill' height map more than once? My sister'll kill me if I don't make her a pretty meadow with streams, geez.
Also, I am still confused about terrain masks. I would appreciate if anyone can give easier advice! MY working out of terrain masks:
1. Load your height map.
2. Change to RGB not greyscale.
3. Red - middle areas. Green - mountainous areas. Blue - deep areas.
THEN I DON'T KNOW.
I understand height maps and im working on one now.
