Bug? GI without Lights.

[felted]

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.

Perfect. Now it works.
Thank you very much!
