coincidentally I had alook to see how normals react in the alpha last week hoping to see some shiny ass raytracing change with the angle of the normals but they don't interact together, seems to be one or the other. Even then they were very slight and acted more like a bump than normalmap and weirdly negated the texture... or perhaps I just did it retardedly lol.
But yeah I'd love to see it work tho.
