Thank you for that. You may be right, since you can set up shadow cascades separately, but I would really like to use just the distance field shadows since they’re so low cost. The landscape doesn’t work with the distance field shadows, though, so the far cascade is necessary to make sure the ground is casting shadows. From my experiments, you can get away with setting the far cascade pretty low, though, so you can get a lot of render time back that way with very little impact on the visuals as long as the trees are still shaded.
Anyway, I’ll keep my fingers crossed that it’s an easy fix.
EDIT: I noticed if you reverse the situation and set the distance field shadows lower than the far cascade, the distance field shadows will get cut off as well, so they just have to be exactly the same length to fade correctly.
