Here is a snapshot taken from the game Star Ancestor currently in development at Obraz Studio.
There is no trick or final improvement on this image. It was captured directly in the game from a GeForce3.
For the technical side, you can notice here a massive use of HDRI for illumination, diffuse and radiosity.
Typically, we use a lightmaps exporter from our 3D Software -Lightwave 3D- and import them under our tools to be managed by the graphic's renderer through modulate context.
We use a proprietary 3D engine called OZOS (ObraZ Operating System) which is currently used for both RT applications and CGI previewing (pub, video clip, etc...).
