This is what I first came up with. It's wrong.

Shadow and light do switch sides, but the core/edge of shadow does not.
(The camera here is at a very slight angle, so not 100% straight on.)

On top is top view and how the light hits/is blocked. The red line on the right is the edge of the shadow.

Let's make this a note sharing thread. Or basic form practice thread.
Or tell me, if you have any requests for simple lighting setups with basic shapes in blender.

What happens to gold under different colored lighting conditions? It's impossible to find references on this.

I'm too stupid to understand this one even though you already explained it.

Wow. So difficult.

This just doesn't look right. It's lit the same way it would be if the light source was behind it around the bottom right

>>3089426
Why would anyone have trouble extrapolating this? Are you clinically retarded, anon?

Also what shape would the highlight be? It can't be a circle in this case

Lightsource for this was a square plane, that emits light.
With matte material, the highlight won't be noteably different to that of a point lightsource though, see pic. If the material is very reflective, it would be square shaped, distorted by the form which reflects it.
