Not affect an object with a light
Hi guys,
I have to render a chapel with a tainted glass and my cam is indoor, the light come only from my windows.
So I have to boost my env light to have a good ambiance. But when I do this my tainted glass is grilled.
So I want to not affect the tainted glass with the EnvLight, but with my square light just behind.
Do you have tip to do that ?
(at least I try to make a set for the tainted glass and substract it in the light set but it's doesn't work )
Thank you in advance for the answer

Re: Not affect an object with a light
This is a job for the LightOverride node :
Using the LightOverride node, you can modify the light attributes per objects. Yes !
Add a LightOverride node in your RenderGraph.
Connect the taintedglass objects to it.
Set the name of the EnvLight in the LightOverride -> Light attribute
Add the Intensity attribute and override it to 0.
This will set the envlight to 0 for the taintedglass objects.
All is explained here :

Have fun.

Hi SebCbien,
Make a specific Light Set for theEnvLight instead of the default one called "Lights".
Connect every geometries to that new set but the tainted glass.
Edit : grilled
Anyway there are many ways to achieve what you want.
