I have encountered a Bug in Visionaire 5 which was not there in 4.2: It seems like the Lightmaps are somehow scaled faultily.
The Bartender is quite a Bit darker (particularily noticable because his Arms, being but a mere separate Scene-Object, are unaffected), the Woman at the Bar is slightly brighter, and the Protagonist is massively brighter -- in Fact, she is at full Brightness, and if I were to move her a little Bit to the Right, she would suddenly be tinted as if in the Shadows, but should be no such Tints in both of these Areas, the Shadow-Area should be at the most outer Part of the Scene. I have noticed the same Problem other Scenes as well, so I know it's a general Bug.
