This is mostly dynamic lighting and I also want dynamic so no built shadows. As for resolution I tried going higher and higher but no use.
So far the best results came from manipulating the cone angle, particularly around the mentioned degrees of 37 and 53. Weirdly enough in between, above and below are all worse. Not really sure why but so far I’m glad I have some result.
On the other hand, my actual goal would be completely eliminating the blurring of shadows based on distance as in sharp shadows until to the very edge of the light range but I guess that can only be done if I change the engine itself.
