; Anything following a semicolon is a comment.
; Blank lines are ignored.
; All strings are case sensitive.

; First let's start by understanding lighting.
; We'll use a white texture and nearly white color ramp (254,254,254).
; First we'll make an entirely ambient white scene without shading.
; * Set Ambient to 255, 255, 255.
; Now let's turn shading on to the max.
; * Set Ambient to 0,0,0.
; Now let's find a happy medium.  Note that Ambient and Diffuse components don't
; have to add to 255, but they typically do because otherwise you get oversaturation
; or you just dim the picture.
; * Set Ambient to 145 145 145.
; If we want to make shadows cooler, we can make the blue and green more ambient
; while making the red more diffuse.  That means the blue and green will be there
; even in on the slopes, but the red will get cut out on the slopes.
; * Set Ambient to 140 160 190.
; Except for subtle things like the cool shadows, 
; changing the chroma of the ambient and diffuse doesn't work all that well, because
; if you also have chroma in your texture or color ramp, modulating colors
; doesn't look natural.
; *** Try texture without color ramp.
; Without color ramps, we have nice texture under our feet, but the mountains in the distance
; have no texture because the art maps fade away quickly.
; *** Try color ramps.
; With color ramps, the mountains in the distance look great, but they don't provide
; interesting texture for the ground under your feet.
; feet still
; *** Try blending texture and color ramp.
; Modulate doesn't work very well except for shadow maps, because we want chromatic
; variation from both the color ramp and from the art map.  If we multiply two textures
; with chromatic variation, the results are dark and unnatural.
; Alpha blend, on the other hand, looks great.  You just have to keep in mind when
; making your artmaps that you should increase the contrast since the entire artmap
; will be averaged with the base color ramp value.  Color ramps with chromatic variation
; are much more interesting than color ramps with intensity variation, because the shading
; is already providing texture in intensity to the scene.
; *** Try sedimentary rock, different height ranges of color ramp.
; *** Try all the testBumpinesses.
; *** Try the random tiler.
