I'm learning about SceneKit's lighting model, and I noticed in Apple's official documentation that the explanation for 'constant' is:
This means that 'constant' should consider both ambient light and diffuse light.
However, when I placed an ambient light with a yellow color in the Scene Editor, I found that the 'constant' model doesn't seem to consider ambient light. On the other hand, the PBR and Blinn models correctly reflect the yellow ambient light. I'm curious to know why this is happening.
