Hello.
This is very annoying…I’m using exponential color mapping in vray and raised the light multiplier to 2.5 but this intensity burns the shaded preview.
Is there a way to control exposure of the shaded preview??
Thanks
Wel basically if your viewport shading is overbright, you could do the following:
In your viewport right click perspective (or wathever view you are) choose configure.
In the dialog check default lighting and choose 2 lights
However, if you are using IES lights, it might be the videocard. There has been a topic on that.

Or hit: ctrl + L
Second that !

That it 
Would be nice tou have another multiplier for the shaded preview though..
Thanks a lot!!
global lighting in the environment rollout doesnt work for you? its a multiplier which has no effect on the render but it does on the viewport
