Fractured Cube Breakdown

Requires a pre-fractured model (for example made in Blender, using the Cell Fracture addon). But importantly, the positions of the origin/pivot of each fractured piece has been baked into mesh data (UV channels).

Unity-HDRP-GPU-View-Cone: View Cone, Field of View, Sight Cone - done with custom Shadow Mapping in Unity HDRP

The technique used is basically the shadow mapping. Rendering the depth texture from the eyes of the enemy, then checking which spots are visible to the player AND the enemy and only drawing on overlapping pixels. The performance cost should be like having a spotlight with shadows turned on.
Since the latest few HDRP Upgrades the system doesn't work in builds anymore. So consider this repo just for learning purposes on how to theoretically set up custom shadow mapping
