Beginner's Guide to Unity Shader Graph: Create Immersive Game Worlds Using Unity's Shader Tool

Discover how shaders can enhance your game and mesmerize players by making graphic gameplay elements more realistic and attractive. This book provides easy-to-follow recipes that will show you how to leverage the Unity Shader Graph to create more immersive, enjoyable games.

Author Álvaro Alda takes you through each effect step by step, so that you gain a foundational understanding of how they are created using the Shader Graph tool. Practical projects help you put what you're learning into context, from simple effects like 3D scan lines to more complicated effects such as black holes, bubble particles, water, and even interactive snow. Twelve different effects are demonstrated, to cover almost everything related to shader graph.

On completing this book, you will have a thorough understanding of the Shader Graph tool and samples to replicate and continue learning from. Whether you are an indie game developer or technical artist, Beginner's Guide to Unity Shader Graph will give you the confidence to use the Shader Graph tool to create games that will keep players glued to their screens.

What You Will Learn

• Understand the purpose and use of every node and function in Shader Graph
• Gain a working knowledge of the mathematics needed to use the fragment and vertex shaders
• Create complex effects with Shader Graph using post processing and taking full advantage of the URP of the Unity 3D engine
• Develop procedural textures using mathematical nodes in Shader Graph

Who Is This Book For

Technical artists, indie developers, and game developers with little to no knowledge of shaders, but who have basic knowledge of Unity. As the Shader Graph in Unity is similar to other shader editors like Amplify, Blender material nodes and Unreal shaders, this book can be used as reference when working with other platforms and game engines different from Unity.

發現如何使用著色器增強遊戲，並通過使圖形遊戲元素更加逼真和吸引人來迷住玩家。本書提供易於遵循的食譜，將向您展示如何利用Unity Shader Graph創建更具沉浸感和樂趣的遊戲。

作者Álvaro Alda逐步引導您了解每個效果，以便您對使用Shader Graph工具創建效果的基礎理解。實際項目將幫助您將所學應用到實際情境中，從簡單的效果如3D掃描線到更複雜的效果，如黑洞、氣泡粒子、水甚至互動式雪。展示了十二種不同的效果，涵蓋了幾乎與著色器圖形相關的所有內容。

完成本書後，您將對Shader Graph工具有全面的了解，並有樣本可供複製和繼續學習。無論您是獨立遊戲開發者還是技術藝術家，《Unity Shader Graph初學者指南》都將使您有信心使用Shader Graph工具創建讓玩家留連忘返的遊戲。

您將學到什麼：
- 理解Shader Graph中每個節點和功能的目的和用途
- 獲得使用片段和頂點著色器所需的數學知識
- 使用後處理和充分利用Unity 3D引擎的URP，在Shader Graph中創建複雜效果
- 使用Shader Graph中的數學節點開發程序化紋理

適合對著色器知識幾乎一無所知，但具有Unity基礎知識的技術藝術家、獨立開發者和遊戲開發者。由於Unity中的Shader Graph與Amplify、Blender材質節點和Unreal著色器等其他著色器編輯器相似，本書可作為在與Unity不同的平台和遊戲引擎一起工作時的參考資料。
