Gone are the VSM and ESM methods to compute the shadows in Blender 2.81. No More. In place of that we have now the PCF method.
In this video I show a few tips to get rid of light leaks, if you still have. (Bear with me, I suffer at the moment from hay fever I believe. But did the necessary cuts.)
For some background info, check this wiki page.
How do you experience the new method to compute shadows? Do you have some more tips for the Blender Community?
