how to fake global illumination:

1. for each point on a surface, ask yourself "if I was a tiny bug sitting on the surface of this object, what would the sky look like?"
2. think more about being a bug
3. enjoy thinking about being a bug
4. make a bugsona
5. make friends with other bugs
6. find a function that approximates the average sky colour. this will be a proxy for the hemispherical integral, and add that on top of any specular contribution

this is how I did the shading on the boat in international shipping. well, I skipped steps 2-5 because I'm already a fish

@SuricrasiaOnline ok but
you know
world is flat so... how 2 discus illumination
