Visible light makes objects brighter

Hey guys,

Might there be a setting in a light that tells the visible light not to brighten up the contrast of an object within its range even if the light is set to exclude the object?

Thanks,
Brian

so punch a hole through the 'visible fog' (so to speak) from the object to the camera? I don't know of any way other than using an Object Buffer for the object and doing a multipass render and using the object buffer to add a layer mask in the Atmosphere layer in post

Hey Brian!

I had this same question. in my context, I am producing a high resolution Planet Earth and I'm using a Light with Visible Light turned on to produce some Atmosphere lighting effects wrapping around the earth surface. I didn't like that the visible light some what lightened my blacks on the dark side of the planet, so I was looking for a solution where I could limit the fall off of my visible light.

I was searching and found this:

"In the Details tab of the light use Near Clipping."

This worked!! In my example, my planet is 1000 cm's and I set my Near Clip from 500cm to 500cm and boom, I got a perfect rim of visible light that I can now tighten or expand depending on these values, and I got the blacks back!!

I hope this helps!
