Dust Particles with Lights & Shadows [WIP]

About time for another video, isn't it? We thought it would be cool to have some kind of dust particles floating around near the windows in our game, so I started experimenting with dust + lit particle effects. Unfortunately the DPSF particles won't receive any of the Sunburn lighting calculations, so I made a basic particle system specifically for the dust trails. Currently they receive light and can cast shadows etc. The effect is a bit exaggerated to create a lightbeam effect.

Be sure to watch it in HD if you'd like to see any dust at all! :)
