Delighting: Possible to create "negative" light? Or other tips?

[BeneZ]

Hi,

is it somehow possible somehow to invert the lighting from a source, for purposes of delighting?
Imagine I have a known light direction, which is baked into a textured object and I want to neutralize it...

Thanks

It is, but the results can be a bit odd. You can set the diffuse and specular contribution values to negative numbers on any of the V-Ray Lights.

Don't know if it's possible, but I wouldn't go that route. There are plenty of techniques that let you delight using just regular lighting tools and AO without getting into negative lights. You could even just use one of the free delighting tools that are floating around (I think Unity has one), though I've never tested any of them for quality.
