wip comments please

hello i need a little help with the lightwall how can i make it have a sharper fall off so the room isnt so yellowy greeny

thanks

how is the wall built?
check the renderer without GI, and see if it’s direct light doing that thing.
In which case, you may duplicate the lights, exclude the yellow ones from lighting anything but the wall, and change the color of the duplicated lights to something that suits your needs (after of course having them exclude the wall from lighting).
If it’s GI, then maybe an override material will help.

I have a yello vray light and glass with wax shader in front of it coloured white

so i guess ill have to overide the ceiling although it is sort of growing on me!

you can set the Saturation of the GI lower.

Indirect Illumination > Post-processing. Set it to .25 or .5. You’ll end up with less color bounce but the same lighting.
