override material for gi

[lightingparty]

Hi every body,
maybe it could be interesting to add an override material (like in vray) to override gi . for exemple in interior scene, when you have a dark floor, you have to increase exposure a lot to have a good lighting into the room (like in photography) and so behind the window everything becomes overexposed. to avoid that, the only solution i have found is to override the dark floor material with a near white material for the gi floor ( i don't like it but...)
Maybe there's other solutions i don't know but if someone have an idea to a different way, i m interested in it!

best regards and well done for corona which is propbably the best render engine i have ever seen

Rayswitcher is already implemented and will be available in next public build. Currently, you can simply clamp the exposure outside of the window by increasing highlight compression value.

This was already implemented, and will be available in the next stable build.

PS: I would suggest first trying to light the room without fakes, you might find that with Corona you won't as many fakes as you are used to.
