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.

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.

Four Color Gradient - One of my favorite effects in After Effects is the 4-Color Gradient. I like it so much I wanted to recreate in a shader.

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.
