Beginner's Guide to Unity Shader Graph (eBook, PDF)

Create Immersive Game Worlds Using Unity's Shader Tool

• Format: PDF

Produktbeschreibung

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.

You will:

• 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
