Weird sun settings...

[Anonymous]

Hey Dwight,

Any idea what's up with this?

A one percent change in the Contribution to Ambient (CtA) is causing crazy color shifts.

[Anonymous]

...and even more bizarre... add a little color to the ambient and...

Note that the effect is dependent on all three settings (Intensity, Contribution to Ambient, and Ambient). I have only checked a small number of conditions but the point of the change due to the CtA seems to go up as the Ambient goes down.

BTW: This is not just a preview glitch. The rendered colors are just as bizarre.

[Dwight]

Yeah.

It is a long time thing.

It is always best to keep the ambient contribution minimal.

Yet another whacko behavior.

Thanks.

Does the Contribution to Ambient do anything useful?

[Dwight]

What it is supposed to do is mitigate shadow strength and reduce the chroma of the ambient light but i never could control it properly. Seems irrelevant in LightWorks. However, OpenGL renderings can have interesting tints when you play with sun and ambient colors. Haha.
I just misspelled "sun" as "sin."
"Sin color."
Everyone knows sin is scarlet-colored.
