We´ve a problem with pssm.
When sun_angle.tilt is low, the shadows are disappearing at certain camera angles.


sun_angle.tilt is low, shadows are visible:


sun_angle.tilt is low, camera angle has changed, shadows are not visible:


sun_angle.tilt is high, shadows are visible:


sun_angle.tilt is high, camera angle has changed, shadows are visible:



If I comment #define DEBUG_PSSM in the shadowmaps are shown, but they are not rendered. What could be the reason for this behavior?

Not sure what you mean by this.

In shadows.c there is a define, called #define DEBUG_PSSM.
If you comment that in, the shadowmaps are shown as bmaps.
I can see the shadows on these rendered bmaps, but the won´t appear in the level:

Ah, so the depths are read and compared, just not projected at certain angles... That sucks. If i knew a little more about complex shaders I'd help

Did you find any fix for this problem in the meantime?

Yes, it was caused by a shader that we used for the fishes. It influenced the PSSM shadows and caused the bug. It works fine and without problems now.

i have this problem too in shadow_stencil
