I got stuck when trying to redesign my engine to better support materials that depend on multiple render passes. So I started working on a cloud system instead:)
The system if fully dynamic and the clouds move and deform. The lighting is a (rather) simple trick but looks quite nice. I got the basic idea from an article by Michael Gehling in last months GDMag. I just modified it to suit my needs. The main problem I have is that it's very hard to tweak the system to look good in all situations. Settings that look good at dawn look crap at noon and vice versa. But I think I can solve that by interpolating settings over the day-night cycle.
Another problem is that things are getting rather costly as you can see on the fps counter:) So far I've done no optimizations what so ever so I think I can squeeze quite a few more fps out of this baby.
Here's a few new screenshots:

Yeah you're right, it's just a plane with layers of perlin noise so that's why they look a bit flat. I use normal maps for the lighting and it helps a bit.
I think that volumetric clouds like the ones described by Mark Harris is overkill for a FPS style game. The player will probably be focused on things on the ground and not notice the flatness of the sky:)
