Issue #29 - Unity 2019.3, Shader Showcases And Optimization, Types & Memory, How Tos, And Free Courses And Assets
2019.3 is officially out with a bunch of stuff to catch up on. Check out the official blog post and the video recap below for what it contains.
As always, lots of great shader material this week. From coding them, to shadergraph implementations, to optimizing runtime, there is a little bit of everything.
If you want something more immediately practical to your own game, check out some of the video how-tos below.
Unity 2019.3 is now available - This release features a brand-new Editor interface, new Input System, faster in-Editor iteration time and lots of other improvements. The High Definition Render Pipeline and many 2D packages are now verified for 2019.3.
Switching to two releases in the 2020 TECH stream - With Unity’s evolution to a package-based feature-delivery system, we will reduce the number of TECH stream releases in 2020, while delivering continuous updates for all feature areas throughout the year.
Unity XR platform updates - Amidst a period of innovation for XR, we want to ensure Unity remains the best development platform for creators and our ecosystem partners. We’re excited to announce our new XR plugin framework designed to empower the ecosystem and provide guidance on how this impacts development in 2019.3 and beyond.
Explore Revit models in VR with Unity Reflect - Unity Reflect makes it easy to bring Building Information Modeling (BIM) data into virtual reality (VR). Learn how you can use the Unity Reflect VR Viewer to conduct immersive design reviews with Autodesk Revit models.
Unity Pattern: Stateless Scenes - Unity does not provide much direction on how to transfer game state between scenes. Some community suggestions are singletons, static variables or DontDestroyOnLoad. But these have other effects that you might not want. Here, I will share a pattern inspired by functional programming I call Stateless Scenes. This pattern, inspired by asynchronous APIs, leads to a much cleaner design.
Save Memory on Disabled GameObjects - One of my students, Ryan, asked me last week how he could rescue the memory Unity was stealing from his game because of disabled game objects. Luckily, he was using Addressables, so I prepared an experiment...

Allocating Memory Within a Job - What do you do when a job you’re writing needs to allocate memory? You could allocate it outside of the job and pass it in, but that presents several problems. You can also allocate memory from within a job. Today we’ll look into how that works and some limitations that come along with it.
My take on shaders: Stylized tree leaves - One can take many approaches when it comes to making trees, and since most tools out there take a procedural approach, it’s not easy to set the models up manually to achieve certain effects.
World space UVs & Triplanar Mapping - This post includes an introduction to using the Position node to sample textures rather than using mesh UV channels, which is also the basis of Triplanar mapping.
Using Unity’s ShaderVariantCollection - The game was hitching sometimes when an enemy appeared and when it exploded. It only seemed to happen some times and with some enemies. I’ll explain what I found when I broke out the profiler and then I’ll provide one possible solution using ShaderVariantCollection.
How to display in-game messages with Unity Particle System - Developing our game The Unliving we decided to find the possibility to display in-game messages with numerical values such as damage inflicted, reward value, the number of health points restored and others, using the Particle System. We decided to do so in order to get more opportunities to customize the effects of the appearance and further behavior of such messages in future. Also, it was difficult to implement this solution using standard elements of Unity's UI-system.
Compiler Options - Do you want to add C# compiler options to your unity project? Like removing unwanted warnings from being thrown anywhere on your project? Create a csc.rsp file. Add in the compiler options u want to include. (eg -nowarn:0649). For even more info check here.
Analysing Performance Problems with Xcode Performance Tools, Part 1 - Xcode has a very simple tool for checking which part of the system is under the heaviest load.
Orbit Camera - This is the fourth installment of a tutorial series about controlling the movement of a character. This time we focus on the camera, creating an orbiting point of view from which we control the sphere.
Introducing Python for Unity Editor - We are releasing a Preview package of Python for Unity which allows access from Python to the full C# API of UnityEditor, UnityEngine, as well as your own C# APIs added to your Unity projects, and running Python code from within C#.
edX Free Course - Introduction to video game development with Unity - In this introductory video game development course with Unity you will learn in a practical way with numerous examples that will guide you step by step: Getting to know the Unity interface, what the fundamental elements of the Unity engine are, and to develop your first games.
Unity 2019.3 Released - Unity 2019.3 was finally released and finally a ton of previously preview features are now ready for prime time such as the URP and HDRP programmable pipelines, Shadergraph, new 2D tools and terrain tools and more.
Luigi’s Mansion’s Ghost Capture - Capturing a ghost in Luigi’s Mansion is a very satisfying mechanic and the animations add a lot of personality to the game - so I thought it would be a good idea to try building a similar effect using Unity!
