Best shadow quality for Static GI ArchViz
i just started playing with unreal engine 3-4 weeks ago. The system is so fun but also so confusing since there is so much parameters and dynamics. So.. my question is how can i get best shadow quailty for GI. I read about distance field shadows but also area lights for stationary lights etc. Which gives best quality? Or should i use them together? Here is the image of my problem with a stationary directional light baked at production. area shadows enabled. shadow exponent is 1 instead of 2.
as you see they are fine at window side/ starting area but its too jagged at end side. i like that expanding shadow effect instead of full sharp shadows but that distortion bugs me too much.
Distance field shadows work with dynamic lighting and it has it's limitations. What you are seeing with area shadows in the screenshot is because of the lightmap resolution of the wall i believe. You'll need to use higher res. lightmaps in certain situations for area shadows, which is also stated in the documentation. Also disable Compressed Lightmaps in World Settings > Lightmass Settings if you havent already for better lightmap quality.
