Creating a 3D Flag in Blender

How to make a 3D flag in Blender

Blender 3.5, the free 3D package, has introduced new features that make it easier to work with geometry nodes in manipulating objects in 3D space. In this practical article, we will learn how to create a 3D flag effect using Blender’s asset browser and geometry nodes.

Blender 3.5 comes with a new asset manager that allows users to create their own toolbox. When you first open the asset manager, you will find example assets for hair and hairstyles. Previously, the developers did not provide any content to keep the download size manageable. However, these example assets are based on simple instructions and fit well within the package.

Creating visual effects in Blender involves working with nodes, known as geometry nodes in this case, instead of typed program code. Nodes represent individual program functions that can change size, load textures, and perform other operations. These nodes have input and output sockets, which can be connected by dragging “noodles” from socket to socket using the mouse.

Please note that this article uses terms from the English version of Blender, as the German translation has some gaps and includes terms that are not commonly used. Additionally, most tutorials and instructions, including those created by German users, are based on the English interface.

By following this article, you will learn how to create a custom asset that modifies an image file to create a flag that waves in the wind. This allows you to program your own visual effects using Blender’s geometry nodes.
