View Full Version : Area light distribution
My colleague and i have question: What do need to do with light options for preventing of bottom line appearing...dark narrow line like shadow
That near to the lightsource the angle between it and the lit surface is near 90° so not many photons will reach that area. At exactly 90° no photons will reache the surface. It's a sideeffect of the lightsource beeing perfectly flat.

Based on that analogy...
..tilting the light should solve the problem - but it doesn't
I think it's more like a distribution problem near the light?
Sample distribution will add to the problem. More samples should make the edge less prominent.

Do you think something could be done to improve the distribution at close proximity?
Not without compromising over all light distribution and not without increasing rendertime.
Björn, thanks for reply. Strange, several render engines like fR or vray have not such side-effect.
