However there’s still a “shadow” at the edge to the shadow map that I’m not sure how to get rid of:
(other lines are light/camera helpers)
How do we get rid of that edge-of-shadow-map artifact?
Turning down the resolution from 1024 to 512 (and adjusting blur/samples to get a desired shadow), I can now see three edges of the shadow map:
How do we get rid of those?
EDIT: same problem here: Hide line from Shadow - #10 by Chaser_Code
If I increase shadow.bias to a fairly larger number like -0.1, I get less shadow-map-edge-lines, but the whole shadow is almost gone, so that isn’t working:
It’s like there is a massive depth delta at the shadow map edges.
Is there some way to hook up TSL, re-using VSM nodes, but adding some logic to fade out the edges of the shadow map?
