Hi, I don't know if you still respond here. I implemented your system into my game and I stumbled upon one issue with the shadows that seems to happen after making the soft shadows.
By having a source of light in the right part of the wall, the shadows from the left-down corner seem to flicker the further away is the source of light.
I think it has to do with something about the implementation of the soft shadows because if I have sharp shadows everything works as should be, and I also saw this issue occurring in the Part 5 project base here. You know what could cause this? ill greatly appreciate.
