I'm not quite sure what we have here. Negative light is a feature which can be
used artistically, but then the shadows must be affected too. In your additional
scenes the shadows of the positive light still seems to be not influenced by the
negative light. Most likely we're hunting down a bug here. My opinion is that
negative light gives more artistic freedom but then it must be implemented
correctly. For photorealistic renderings it is not necessary. May be Christoph
Lipka can shed more light onto this issue.
Best regards,
Michael
