How to build Hot Reload For Unity

2 hot reload tools have been released recently (shared the previous one here before).
The author of this one also provided a tutorial with basics of the hot reload implementation.

water-shader-unity: Simulation of water in Unity

Realistic water was achieved by implementing selected water effects:
- Reflection
- Refraction
- Caustics
- Waves
- Flow
- Underwater fog

TextureMerge: Software to merge (or pack) textures into image channels, producing one image with up to four textures.

The tool to prepare assets for a very common optimization technique where you pack up to 4 grey scale textures into one by using different channels to save memory.

Unity Threading; Provides helper APIs for multithreading in Unity.

Provides:
- Simple Threading
- Async Threading: helper methods to access to the Unity main thread or background threads using an async/await style
- Unity Coroutines: helper methods to reduce allocations in Unity coroutines.
- New Coroutines: a reimplementation of Unity coroutines that returns a value type instead to avoid allocations.
- Unity Jobs: helper methods to execute jobs in the Unity Job system.

UnityURP-MobileDrawMeshInstancedIndirectExample

A simplified sample that demonstrates DrawMeshInstancedIndirect API on mobile platforms. Only contains a simple CPU frustum culling (not even a quadtree) -> minimum compute GPU frustum culling (no Acceleration Algorithms), then just 1 DrawMeshInstancedIndirect call.
It also contains a RendererFeature(GrassBendingRTPrePass.cs) to render an offscreen RT(R8), which renders top-down view grass bending area (by trail renderer following moving objects)

BurstCollections: Burst friendly (special) native collections for Unity

Contains:
Native2dTree
NativeAccumulatedProduct{T, Op}
NativeArray2d{T}
NativeBoundingVolumeTree{T}
NativeIndexedArray{Id, T}
NativeIndexedList{Id, T}
NativePointQuadtree
NativeStack{T}
NativeStackedLists{T}

In the repo there are use cases when these collections can be used to solve particular tasks.
