It’s almost ready. Got soft shadows working thanks to temporalAA shifting the light angle:
The shadows are a tad noisy due to the tempAA which I don’t like.
I almost have a version that doesn’t need TempAA using “proper” cone trace approximation working. It gives really nice smooth shadows on the ground, but introduces horrible stepping on the curved surfaces. I’m sure I will figure it out eventually:
edit, ok that was quick. still a bunch of cleanup so calling it for now but should have something to post tomorrow.
The tiny bit of artifacting that is left is from web compression since I copied the height image from here. Notice the blocks on the slopes.
