A work-in-progress capture of one of the shots going in my demo reel, from my fairy forest scene. Aside from the leaning tree and the rocks, everything else in the scene is hand-made by me. Currently working on sculpting the rocks for the level.

Video captured in-game, in CryEngine SDK. Did some work with particles with the faeries flying around and the faeryfire flowers in the log on the right, as well as the falling leaves.

You'll also notice that all of the vegetation in the scene has proper wind bending applied to give that added realism... another nice feature cryengine has.
