Thank you :) > The See A Demo link does nothing for me... This is bad. It must be some corner case, maybe some Chrome add-on interaction (we tested the button with vanilla Chrome on Windows)? We'll have a look at this. > The controls in the scene feel a little sluggish This is a good suggestion and not hard to add, we'll work on it, thanks :) > I'd like to know about what lighting/rendering tech you're running For diffuse lights, we use a static, precomputed light map split into two channels (chroma and luma) to be able to take advantage of HDRI (this way our light map can make the original colors brighter, not only darker). For specular lights we currently use only cube maps with different resolutions (some also have a blur effect added). There is a lot of room for improvements in our specular lighting, we plan to experiment with specular cube maps, or dynamic specular lights that take into account strongest lights for a given fragment.
