Taking Blender to the Next Level

By: Ruan Lotter

Overview of this book

If you're ready to start exploring the more advanced workflows and processes in Blender to create intricate 3D models, then Taking Blender to the Next Level is for you. This book focuses on a few different VFX-related workflows such as geometry nodes, organic modeling, 3D camera tracking, photogrammetry, sculpting, compositing, and physics simulations. You’ll learn how to use geometry nodes to create dynamic motion graphic scenes as well as perform 3D scanning of real-world objects using photogrammetry. You’ll also find out how to model, rig, and animate your own 3D characters from scratch. Next, you’ll progress to using simulations to break objects apart and then use cloth and hair simulations to add realism to your 3D creations. Finally, you’ll go over the final render settings and export your 3D animation masterpiece as a video. By the end of this Blender book, you’ll be able to model your own 3D characters, objects, and landscapes; rig, animate, and texture your characters; 3D track live-action footage; and composite your 3D characters into live-action scenes.

UV unwrapping and texture baking

In this section, we will focus on UV unwrapping our low-poly model as well as texture baking. We will be baking textures from the high-poly scanned model into our low-poly model. Let's get started!

UV unwrapping

Let's begin by importing the low-poly model that we have exported from Instant Meshes into Blender:

  1. Open the Blender project you saved earlier in this chapter. Then, click File | Import | Wavefront (.obj) and browse to the folder where you have exported it.
  2. Select Model_LP.obj and click Import OBJ at the bottom of the dialog box.

The low-poly model will appear exactly at the same location as the high-poly model that's currently in this project. You will notice the slight overlap in 3D Viewport:

Figure 6.14 – The low-poly and high-poly models overlap slightly in 3D Viewport

  1. Let's make sure our models are named properly in Outliner. The low-poly object should be...
