![]() ![]() If the option is disabled no shadow rays are traced during the direct light calculation causing objects to lose their shadows. We also added an option to make emitters double-sided. The emitter on the left of the example below has the option "Double-sided" enabled. We added a new option "Transparent emission" to the emission nodes to allow the user to choose whether the emission power should be scaled with opacity or not. Until now, transparent emitters were always taken fully into account even if they were transparent, i.e. They behaved as if "Transparent emission" is enabled. This is useful if you want to control the light in your scene without your emitters being directly visible. – Improved rendering of non-uniformly scaled emitters But there are cases when transparent emitters should not emit light, for example if you would like to modulate an emitter surface using opacity. Until now, non-uniformly scaled emitters were rendered incorrectly. – Importance sampled texture environment for all textures The problem was that in that case the direct light sampling was done non-uniformly, too, resulting in artifacts in some corner.
