Unfortunately, one problem I am encountering is that shadows cast by geometry located to the side or behind the camera get clipped, leading to a number of artifacts. For example, standing outside a building with the "sun" to your back, the shadow map correctly projects the outline of a doorway onto the floor. However, once the camera enters the building, the wall is clipped and this causes the entire room to be illuminated. This is a very noticeable and undesirable effect. How can I mitigate this problem? [*] I had high hopes for PSSM based on reading about the technique but so far neither osg 2.8.3 nor 2.9.10 produce correct results for me.
