Thanks guys. It's an improvement allright, though I could have thrown in a lot more veggies. For a commission I would, but this was merely intended as a test for the tower.
Regarding the armor; I had a refraction index of 4 at first, lowered it to 2.5. Still too much? I was also working on bronze, and found that multiplying the RT reflection with a color will do that trick. The colors I still have to work out, had a greenish tint at first, but these helmets were polished and shiny new in those days, so no verdigris like old bronze (though that would be nicer).
