Overview of this book

Want to transition from Godot 3 to 4? Look no further than the Godot 4 Game Development Cookbook. This comprehensive guide covers everything you need to become proficient with the latest GUI, GDscript 2.0, Vulkan 2D/3D rendering, shaders, audio, physics, TileSet/TileMap, importing, sound/music, animation, and multiplayer workflows. With its detailed recipes, the book leaves no stone unturned. The Godot 4 Cookbook begins by exploring the updated graphical user interface and helps you familiarize yourself with the new features of GDscript 2.0. Next, it delves into the efficient rendering of 2D and 3D graphics using the Vulkan renderer.

Showing off SDFGI

In this recipe, we will download a 3D asset so that we can see how signed distance field global illumination (SDFGI) looks and go through all of the settings to see what they do. SDFGI is a real-time global illumination method that uses Signed Distance Fields (SDFs) to create lighting in real time.

We will also look at Screen-Space Indirect Lighting (SSIL), which works with SDFGI or VoxelGI and is indirect lighting that allows diffuse light to bounce off of nearby objects.

Getting ready

For this recipe, open Godot 4 and start a new project called Chapter 3. Go to the https://polyhaven.com/a/ship_pinnace website and download the free glTF 2.0 file using the drop-down arrow. Double-click the ZIP file and extract the file to a new folder called Ship Pinnace or whatever you want to call it:
