Hello Jason,
Thanks for the help.
The steeping is well visible in my render pass' camera, not only in the
threshold but on large parts of the roundness of objects. So as I use
this shadow pass as an alpha in composting, it's annoying.
But your post made me think of other options to tweak:
- In Geometry approximation > Poly mesh > I increased the subdiv level
from 2 to 3 and got smaller "steps".
- In Geometry approximation > Poly mesh > I increased the discontinuity
angle from 60 to 120 and got more softness.
- In the light settings > soft light > raytraced soft shadows > I set
it to 3 and 15 and got a bit more softness, but it seriously increased
rendering time.
What bugs me is that the steps are still here. Smaller and softer but
still here.
By the way, I didn't find the option to turn off "cast shadows on
visible faces", could you help me on that?
Thanks,
David

That stepping always occurs, (revealing object polygons without

happenning at the lit/shaded threshold of objects.
But normally isn't visible, as it happens slightly beyond the maximum
reach of the light on an object
(will show-up in shadow only passes)
And should similarly (normally) become invisible once you comp your
shadows in, on a pass with that light only.
Of course if you comp that on on the final with other light sources
you'll see the stepping,
in that is the case, you can turn off "cast shadows on visible faces"
and voila!
