Title: Bug? GI without Lights.
Post by: felted on 2020-02-26, 13:22:56

Hi,

in my Scene i need a white Background.
So i create a plane with CoronaShadowCatcherMTL and set the color of Enviro/Backplate to white.

The Problem is, that the plane is jet a lightsource and illuminates the scene.

How i can switch of the emitting og GI from the plane?

Regards, Detlef

This is actually expected. To solve this, plug the shadowcatcher material into a rayswitch material's direct, reflection, and refraction slots, and plug a 100% black material into its GI slot.
Alternatively, plug a rayswitch map into the shadowcatcher's backplate, and set its GI color to 100% black.
