The measurements of the model wall thickness are written above it, please check. The distance is 5mm.
The sun&sky affection isn't so strong, but giving more natural looking results - on sterile tests you can be fooled more easily.
I completely understand how absorption distance falloff works, and that thicker walls should be darker, etc etc.
What I want to emphasize is that I can't get _predictable_ results - on 255 values I get a strong blue tint without going into the black even if the wall thickness is 15mm, and we have two walls there on that cylinder = 30mm - but we still get deep blue instead of black.
Values of 192 or 128 are more predictable - because now we get black on very thick objects, while still retaining the COLOR on 1mm thickness (although it's more desaturated).
And on very dark values, like 10 - we get black everywhere, with a slight tint of color on thin walls - if I make it even more thin (0.1mm) - then I'll get a very faded and desaturated color.
If you look at my table from top to bottom, how different VALUES affect the absorption - for example, on 1mm thickness - you'll see that the transparency isn't much changing, but just the color becomes more faded/desaturated, dirty, and dark.
Or on 5mm thickness (which is equal to 5mm distance in material) - you can see a blue "halo" around on 255 value, which becomes a strong dark substance on lower values.
Or on 15mm - 255 value has very saturated blues.
But most of all - please compare value 255 on 15mm, and value 10 on 1mm - they're very different.
So the VALUE != doesn't equal DISTANCE. It's another control, which lives on it's own, and does the similar, but completely different thing.
It's like the CoronaLights - you can set a color there, and there is value also - you can set a light to 10,2,8 RGB - muddy pink. But why? You have the intensity to control the brightness of the light. But what's most important - wise people added the Temperature to Lights - when you can control just the HUE, because you already have the Intensity control.
Imagine that you should set the Light color, light color brightness (which works completely different than Intensity), and light Intensity again - isn't this "artistic hell"?
But in material absorption - there is no Temperature, HUE, or whatever. There is just color. And you should pick this color brightness by eye, and pick the distance by eye again (which should control a similar thing, but a bit different). And that drives my mind crazy.
