DMotion - A high level Animation Framework for Unity DOTS

DMotion (DOTS Motion) is a general purpose Animation framework and State Machine for DOTS, built on top of Kinemation (Kinemation doesn't officially support any platform except Windows though as one of its dependencies wasn't compiled to be tested on other platforms)

The magic of Material Property Blocks

Use it in situations where you want to draw multiple objects with the same material, but slightly different properties. For example, if you want to slightly change the color of each mesh drawn. Changing the render state is not supported.

.NET Memory Performance Analysis

Even though the title mentions analysis, the first part is purely theoretical and has a gentle introduction into memory management on the OS level and a deeper description of memory management and GC in .NET.
Disclaimer: Unity uses a different garbage collector, but still there is plenty of info in the post that can be useful even for working with Unity, as well as it's definitely a good read if you'd like to look a bit around Unity.

Compute Shaders: Grass Rendering

The title is a bit misleading, as the author still uses geometry shader to generate grass blades, so it doesn't work on Metal. But it is still an interesting example as the compute shader is used to calculate multiple objects interaction with grass.

Frame-specific attacks in Unity

There are a lot of examples where it can be used, but basically it gives more control over animations which gives us more possibilities to implement different features.
