Answers:
1. Raising the ground only seems to make sharp pointy stalagmites. I want to make small and large rounded hills, as well (maybe it can now but I don't know how to.)
LEE: You can use the + and - keys to increase the size of the terrain shaping brush, which will allow you to create more dumpy hills instead of points.
2. I need to be able to select from different grass models, and terrain textures. At this point the textures will make everything look generic (although I do like the grass.)
LEE: At this stage you can only change the grasses model to a different style using the TAB TWICE and veg drop-down slider panel. The idea of spraying different combinations of grass is definitely on our radar as this will make the floor much more realistic (same with trees and shrubs too).
3. The water level is too low and I would really like different water types (ex. some place I water murkier water, bogs, ponds, etc.)
LEE: I have avoided adding much water related features at this stage as there is a strong community push to have 'water pools' instead of a water plane, which would turn our present water plane into a simple large water pool. We can then have multiple water pools and allow editing on them for height, volume, other effects, e.t.c.
Right now you will find we are pretty single minded and are focusing on performance, stability and memory usage so it runs well on a variety of 'real-world' systems (rather that the super elite gaming rigs most of us do not have).
