Great find. Seem like a small company without a huge amount of experience, so it'll be interesting what they can contribute. Claims they're working with Guerilla on developing a lighting engine. What I'm very pleased with is no PR nonsense! It's not an absolute lighting solution resolving all rays to infinity at 300 fps yadayada. It's using known methods...
Worldlight uses a diffuse PRT solution to provide soft light and shadows resulting from direct and indirect illumination by an HDR skydome. On top of this, it adds a directional sunlight term which is correctly shadowed by the world geometry.
The results are good but not too good...
Nothing on dynamic characters though, and no word on use of Cell.
