FIXED AND IMPROVED translucent rendering. FIXED random stuff from rendering over the hand. FIXED hand shading. FIXED blue horses. FIXED translucent lighting on the hand. FIXED translucent lighting on entities. IMPROVED colored shadows. IMPROVED SSAO application to the scene. IMPROVED subsurface scattering and give it more settings. IMPROVED bloom. ADD AgX tonemap and make it default.
