Practical Optimizations

This is a long video, but it's worth watching. The speaker is a great engineer who shares an example of optimization using DOD (Data-oriented design) in Kerbal Space Program 2. Obviously, this optimization technique is not suitable or needed in every game, but when it fits, it gives amazing results.

Unity Shadow Volume Generator (Stencil Shadows): Library for generating sharp shadow volumes in Unity3D.

Shadow volumes are recognized by the CRISP and ACCURATE shadows that they cast. It essentially finds the outline of an object from the lights perspective, and then creates a mesh that casts into the scene.

Text To TextMesh Pro Upgrade Tool for Unity

Helps you upgrade the Text, InputField, Dropdown and TextMesh objects in your projects to their TextMesh Pro variants. It also upgrades the scripts so that e.g. Text variables in those scripts become TMP_Text variables. Then, it reconnects the references to the upgraded components (e.g. if a public variable was referencing an upgraded Text component, it will now reference the corresponding TextMeshProUGUI component).

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

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).
