In Response to Marky
Finally I came around to adding ambient light. Can I have a second opinion on the implementation?
The first/left implementation normalizes the ambient light before writing it to the color texture (which creates a smooth shade from the light color to the ambient color).
The second/right implementation halves the ambient light color values before writing it to the color texture (which creates harder edges, but weak=dark ambient light is not as prominent on the screen).
Normalization:
+ coherent with the rest of the implementation
- weak ambient light such as RGB(50,0,0) is noticeable at the edge of the Clonk's light even underground
Halved values
+ weak ambient light is not noticeable underground
- hard edges
- colors seem to be more saturated when the light is weak, because of the harder edges
The attached picture is just a sample, the .xcf file has more screenshots for comparison.
