So. Is it possible for bricks to cast shadows from light sources? Or will all the shadows be from the sun?
We have to rerender the whole scene at least twice for every shadow casting light source. Imagine taking your framerate and dividing it by (4 + # of shadowcasting lights * 2). In other words, if you get 60fps right now, you would get 6 fps with just one or two shadowcasting lights.
So we are going to just do one directional light for now. Maybe eventually we will allow multiple lights to cast shadows.
