Parallel Split Shadow Map (PSSM) shadow camera setup.
A PSSM shadow system uses multiple shadow maps per light and maps each texture into a region of space, progressing away from the camera. As such it is most appropriate for directional light setups. This particular version also uses LiSPSM projection for each split to maximise the quality.
- Note
- Because PSSM uses multiple shadow maps per light, you will need to increase the number of shadow textures available (via SceneManager) to match the number of shadow maps required (default is 3 per light).
