Just downloaded and tried prorender 2.4 for Maya 2018 and so far I quite like it. There is few thing that I don't understand and can't find any info regarding it.
First when you just create sun&sky in very simple scene like just plane and cube or sphere or whatever to simulate outdoor lighting it is coming out very dark. Then even if you increasing intensity scene start lighting up but there is no sharp shadows how it is suppose to be with a sun light. Okay. I deleted sun&sky and create directional light and again there is no sharp shadows. Could someone explain me what I'm doing wrong? I can upload scene if it's necessary. But it is pretty straight forward, new scene, few objects, create sun&sky, position camera, hit render.
