The Dawn Asteroid... an idea I had during a discussion where we were going over the fact it's a little hard to create convincing asteroids in Terragen that aren't a chaotic mess of displacement or seams from squashed displacement, but than I remembered the Smoothing Filtered so I gave it another shot.
See, the thing is, you can have a crazy displacement that vaguely resembles a shape you want, and then use the smoothing filter to smooth it a much more pleasing shape to than add all your details too. A fractal shader is used after the smoothing to add in some "streaking" and base detail.
The crater marks is a new/basic procedural setup I quickly did as all the past ones (which are still great) didn't offer the smooth effect I was going for.
Looks good.
