![]() In this post I’ll show you how to setup Shader Graph to work with 2D sprites, and then in the follow up posts linked below we’ll recreate some interesting effects seen in real games. This can take a lot of the pressure off of developers in trying to understand the nuances of shaders, while also giving shader developer pros some perks as well as you can now tweak and preview your shaders in real time from directly within Unity. You can then connect these nodes, wiring them up in a drag-and-drop editor, to create all kinds of interesting outputs which can then be attached to a material like any other shader. You can now drag and drop all kinds of nodes including noise generation, logical operators (AND, OR, NOT, etc.), time, world and local positioning, plenty of math operations, texture sampling, and the list goes on and on. Over the last few years, visual shader editors such as Unity’s Shader Graph have started to alleviate that pain point by simplifying the process of implementing hundreds of common shader routines in a node-based editor. They’re written in esoteric languages and have a variety of peculiarities that make them difficult to pick up, but because they’re so important in game development we all end up writing, modifying or at least trying to understand shaders at some point. However it can be quite daunting figuring out where to start and how to write even the simplest shaders. Shaders, those mysterious programs that somehow instruct the GPU how to render objects and effects in our games, are a great way to introduce effects that make your game stand out from the crowd. Change the name of the Shader to something more descriptive like Shader-ShaderLab.Related Posts Animating Rotations through Code in Unity Synchronizing Idle, Walk and Run animations with a NavMeshAgent in Unity Siren Song, Devlog #3: But With More Dogs Unity: Working with Custom HLSL Functions in Shader Graph Unity: Accessing Private and Protected Fields from the Inspector Creating a ShaderĬreate a Shader in the same way as a Material, but selecting Shader in the menu. Change the name of the Material to something more descriptive like Material-ShaderLab. ![]() A new material called New Material will appear in the Project View. Creating a MaterialĬreate a new Material by clicking Create in the Project View and choosing Material. you should now see a gray sphere in the Preview section of the Inspector View for the material. Make sure the plane does not cover the entire screen so you can see the difference between rendering with a shader and without it. Then select the Align with View option from the menu GameObject. Double-click the Main Camera Object from the Hierarchy view and get a Scene View of the plane. Then position the camera so it can show the plane. Click on Create > Plane in the menu Hierarchy View, or try out one of the other methods to do this in Unity. The first step in this scene setup is to create a plane. ![]() ![]() If you are not familiar with Unity’s Scene View, Hierarchy View, Project View and Inspector View, now would be a good time to read the first two sections ( Unity Basics and Building Scenes) of the User Manual. If not, create a new project by choosing File > New Project… from the menu. Configuring a Unity ProjectĪfter starting Unity, you will probably be viewing an empty project. The setup of the plane and the camera is explained, moreover the shaders can work with any geometry without major modifications. The initial examples you are going to use are a plane and a camera pointing at the plane to show the different functionality of the fragment shaders. This section describes how to setup a basic scene in Unity that you can work with. ![]()
