I spent a few hours running some more tests and was able to come up with some clouds that look quite realistic. This program has been out only a month, and we are already doing stuff like this. Imagine what it will be like in a year!
This program already blows Vue and Mojo out of the water (they are still both incredibly capable programs, but can't touch TG2 at this point).
Here are some preliminary results. I pretty much set it up like I did on the 'fake stones shader is the money' post, but with clouds instead of shaders.
These are low quality (ie. 0.2), but only took about 10 mins to render at 640x480.
More tests to follow!
