How to get pure white?

[Cascho75]

I want to have certain elements to render as pure white (RGB 255, 255, 255).

1. My color mapping (exponential) lets standard-material with self-illumantion render in grey.

2. VRay lightmaterial renders white but also illuminates the scene, what I don´t want.

The same is for backround planes with e.g. trees and sky texture:
I want them to render 100% self-illuminated but not to emit light.

Thanks 4 help!

right click on your object with the vraylight assigned to it then select "vray properties" and untick the GI

OR

In material editor apply a vray override material on your vraylightmtl and set it to not effect gi
