We are having some issues that should be obvious from the attached image. Basic corona rectangular lights used but they turn black when looking at them through the glass. We use refraction in the glass material (not set to thin) as we feel it looks much more realistic and the rendering hit isnt that bad when its so thin. But there is this issue with corona lights not showing through the glass. Light emitting materials dont have this problem.
We are using Corona 4 RC3, so should probably upgrade to the latest but hopefully there is something obvious we can do to fix this?
not sure if it was Vray…… in the glassmaterial you could define how many time the lightray should travel between the glass and which Color it should get after Xtimes.
OK, we have tracked it down and think its a bug. If we set the directionality to 0.4 everything works as it should but 0.5 and higher it goes black through the glass. I will put it in the bugs section now.
