Released as part of the source examples for the 4.1 Alpha launch, this was one of the more advanced tech demos showing off the new multi-pass rendering feature in Away3D. The demo uses the famous Sponza Atrium model, a creative commons resource from Crytek, regularly used as a test model for complex shading scenes.

Multiple point lightsources from the flaming torches combine with a shadow-mapped global directional lightsource and fog effect to create an atmospheric experience. The advanced culling systems in Away3D reduce overdraw in the scene for the lights as well as the objects in order to achieve a smoothly-rendering 1st person experience.
