Bonus Part - Directionality
1. Back Lighting
Negative values reduce scattering; positive values increase it. In the example below, it’s the brightest around the value of 0,8. Getting even higher deepens the scattering gradient. At the extreme value of 0,99 we can see only faint scattering close to the light position in the scene.
2. Side Lighting
The light behaves similarly with both negative and positive values of directionality. More extreme values will cut its scattering off entirely.
3. Front Lighting
Negative values increase scattering while positive decrease it. In the example scene, it’s the brightest around the value of -0,4. Getting lower from this point will dim the scattering, with a vague upward gradient becoming visible. At the extreme value of -0,99, we can see no scattering at all.
