Cross-fading 3D model animations; Project-wide layer updates; New demo game.
You can have more than 16 lights in a scene - the limitation is only on how many lights are in the viewport at the same time. So you could for example have 100 lights spread across a level, and so long as only 16 are visible at a time everything will work. The light radius is an important option to make sure far away lights don't count.
