Arron, could you do me a HUGE favor and add this feature to the climate editor...
have a 500 pixel heightmap with 1 large hill on it that we can see from a side view (possibly via the viewer?) and allow us to chance heightfield options on the fly (scale, height etc) for that particular image and allow us to quickly see how our climate looks in real practice so that editing it is much easier?
Hopefully I made some sense.
Edit: Actually, if you've ever used bryce3d, similar to the way that the materials editor does things. I.E. has the little terrain picture in the top left corner so you can see what your material looks like.
