Please add support for negative light values or inverse color. It would be great for creating shadow gobos while using OctaneSky Light or SunLight. At the moment Light that use Image Projection for Gobo add it strenght to overall scene lighting that is not good for exteriors.

Negative light with inverted projection Gobo image would create only shadow without additional light.

It can be done using AOV with Light Mixer mask but it is way to slow to navigate using LiveViewer.

That's fantastic ! I didn't know that you joined to Octane developers team.

Background plates only for reflections would be great too. Simple moveable polygons visible only to relections but not for internal LiveViewer camera ( like HDR Sky maps ) - please :)
