It's Friday, and that means another Digest! I know you are excited, but keep your pants on. This week sees Unity's ML-Agents reach a 1.0 milestone, so no better time to start tinkering with your game AI. Below you will find tutorials on ML as well as assets for behaviour trees and more.
If you are looking to tune your game for performance, there is some great content this week. As well as optimizing for user acquisition, monetization and more.
For the graphically inclined, there is plenty to check out including the release of Unity's Heretic Digital Human project. Enjoy!

We developed some technologies to enable this. You’re free to use these tools in your productions and build on top of them as you see fit.
Here’s what’s in the box: Facial animation systems
• Tools for 4D clip import and processing. When we say 4D, we mean a sequence of meshes captured over time.
• 4D clip rendering with timeline integration.
• 4D frame fitting, allowing detail injection from facial rig.
• Integration of facial rig from Snappers.
• Pose facial rig directly in Unity Skin attachment system
• Drive meshes and transforms in relation to dynamically deforming skin.
• Used to drive eyebrows, eyelashes, stubble and logical markers.
• Accelerated by C# Job System and Burst Compiler. Shaders and rendering
• Full shader graphs for skin/eyes/teeth/hair as seen in The Heretic.
• Custom pass for cross-material normal buffer blur (tearline).
• Custom marker-driven occlusion for eyes and teeth.

Dynamic Walls - demo implementation - This demo project showcases dynamic walls whose sides adapt to the environment used in our upcoming game: Pelagos: Rise of Greece. It contains a working example scene and commented source code. The idea behind it is very simple. Wall has 4 separate sides (front, right, back, left). If another wall is in front, disable the front side. The same for the second wall. If something is on the back of the wall: disable the back wall. Randomize a little for the prettier look and that's all ;)

Yuppy - Game dev: From zero to App Store, as a side project. How and why.
Developing a game is a challenge on its own, and more so if you do it as a side project while working a full-time job. And maybe have a family. This is my story for Yuppy, a collection of mini educational games for iOS and Android. Why I made it, the struggles I faced, and how I eventually managed to finish and actually sell it.
