Description
Is your feature request related to a problem? Please describe.
At the moment PSSM using fixed split distances for splits. This method is ignoring the scene itself. Only far and near planes of a camera brings the value. In this case, depth buffer for shadows doesn't utilize efficiently.
Describe the solution you'd like
It would be a good field to optimize, scale the separated AABB given the objects of the scene.
Describe alternatives you've considered
This is not a necessary improvement.
