Is there a way to get shadow map shadows to stop flickering even when nothing
is moving?
This is what I have tried to no avail.
On the spot light (cone angle less than 90):
Resolution up ( and down).
Softness up and down.
Samples up.
None of these make any diference to the flickering.
On the render panel:
I've played around with the antialiasing and jitter.
On the shadows page I've clicked off rebuild.
If you view your scene from the light is there an extremely large depth to
the objects? In other words, are the closest object to the light and the
farthest object from the light extremely far apart? This can lead to
ZDepth (used for shadowmaps) presision issues in some renderers.
This is often the case if you have a huge ground plane.
You may be able to exclude some objects, to help, or make smaller versions
that catch shadows.
