Unity allows lights to work in mixed lighting mode, in order to serve double duty for both static and non-static objects.

Video ID: 10_SC_TAR

Mixed Lighting

17:50

Because moving objects don't receive global illumination, we can approximate bounced lighting on non-static objects using light probes.

Video ID: 1_SG_TAR

Project Setup

09:41

Let's review the basic parts of the ShaderGraph window.

Video ID: 2_SG_TAR

ShaderGraph Introduction

12:42

In this lesson, we create a glowing highlight using the Fresnel Effect node.

Video ID: 3_SG_TAR

Highlight Shader

11:56

In this video, we replace the solid base color node with the Texture 2D Asset node and allow the user to set a texture map in the Inspector.

Video ID: 4_SG_TAR

Texture Nodes

08:11

Here we create a simple script to toggle between the GameObject and its highlighted version based on mouse events.

Video ID: 5_SG_TAR

MeshHighlighter Script

09:25

In this lesson, we learn how to build SubGraph assets, small reusable fragments of a ShaderGraph that can help you organize your graph as it begins to grow.

Video ID: 6_SG_TAR

SubGraphs

17:53

Here we create a new shader for a sci-fi force field effect. Using the Time node and a sine function, we can add some simple animation to our glowing highlight.

Video ID: 7_SG_TAR

Time

15:08

In this video we use a TilingAndOffset node to take a simple repeatable pattern and fill in the center for the force field.

Video ID: 8_SG_TAR

Tiling and Offset

19:14

Using the Step node, we can take a noise pattern and create a SubGraph that can simulate sizzling electrical patterns to add more surface detail on the force field

Video ID: 9_SG_TAR

Edge Noise (Part 1)

14:06

Continuing with our electrical surface effect, we add some simple harmonic motion to make the texture come alive and then integrate the SubGraph within the main ForceFieldShaderGraph.

Video ID: 10_SG_TAR

Edge Noise (Part 2)

17:01

Here we use the Lerp node to interpolate between two colors and then apply a subtle animation blend to the Rim Color in our ForceFieldShaderGraph.

Video ID: 11_SG_TAR

Lerp

08:53

In this lesson, we use a Position node to create a color ramp/gradient based on a mesh's vertex coordinates.

Video ID: 12_SG_TAR

Position

11:17

In this lesson, we examine how to use our Position's vertex data as both Object Space and World Space. We use a Branch node to add some logic to our ShaderGraph and then set up the Color Ramp as a SubGraph for reuse later.

Description

2019 Update: Check out our new Section on the ShaderGraph! Creating shaders can now be done without writing a single line of code!

Making your Unity games look amazing is easier than you think. You don't need to be great at programming and don't need incredible 3D art skills.

Creating immersive games starts with understanding the secrets of lighting and being able to squeeze maximum value from your technical art pipeline.

This course assumes that you're a little bit familiar with Unity but doesn't require you to have any programming or art experience. We will take you through Unity's lighting toolset and discuss everything from colour theory to shadows to materials that emit light.

More specifically, the course will start off with basic light set ups such as a single point light and build up to complex lighting setups. Among other things, the course covers:

Direct realtime lighting including directional lights, point lights and spotlights.
Global illumination theory and principles, both realtime and baked (pre-rendered).
Emissive materials and how they can be used to make specific items in your scene stand out.
Three- and four-point lighting set ups - how to create them, how to vary them and how to use them for different effects in your games.
ShaderGraph: get started using Unity's visual editor for creating shaders!

Want to get started with Unity 3D from scratch? Check-out our Complete Unity Developer 3D course. Want to create great environments in Blender instead of Unity? Check out our Blender Environment Artist course.

We follow a project-and-challenge approach which means you don't just sit there and watch us, you follow along and flex your own creative muscles to create interesting game moments. We all learn best by doing (rather than just watching)!

You will also be asked to take on a bigger challenge and light your own scene. This serves as a great portfolio piece, or just something to show yourself what you're capable of once you've finished the course.

Unity is a fantastic engine which enables you to make production-quality games. Furthermore these games can be created for Windows, MacOS, iOS, Android and Web from a single source!

This course is perfect for programmers who want to make their game more interesting, for 3D artists who want to triple how amazing their artwork looks, designers who dream of creating cinematic moments worthy of AAA games, and anyone else who is interested in leveling up their tech art skills.

Come and join us in this course now - you'll be amazed at what you're capable of creating!

Note: the project files for this course have been updated to use Unity 2019 with version 2 of the PostProcessing stack. We recommend that you complete the using Unity 2019 or above.

Who this course is for:

Unity developers (or anyone) interested in 3d art
Beginning 3d technical artists interested in Unity3d
No programming or scripting is required for this course!

This is everything I ever wanted in a Unity lighting course - I've been working with Unity for a while, and consider myself an intermediate artist already. But the course still provided me a lot of tips to improve what I'm doing, and provided me instruction for handling the new Unity features (new post processing and Shader Graph), and I'm able to finally get answers to questions I've always found myself asking.
