There are many tools available for creating texture atlases. Here are a few of the most popular:

* **TexturePacker** is a popular and easy-to-use tool that can be used to create texture atlases for 2D and 3D games. It offers a variety of features, including automatic packing, texture compression, and export options.
* **ProBuilder** is a Unity plugin that can be used to create and edit 3D models. It includes a built-in texture atlas creator that can be used to pack textures into a single atlas file.
* **Nvidia Texture Atlas Tools** are a set of command-line tools that can be used to create texture atlases. They offer a high degree of control over the packing process, making them a good choice for complex projects.
* **Texture Atlas Maker** is a free and open-source tool that can be used to create texture atlases. It is a simple tool, but it is effective for creating small texture atlases.

The best tool for you will depend on your specific needs and preferences. If you are looking for a simple and easy-to-use tool, then TexturePacker is a good choice. If you need more control over the packing process, then Nvidia Texture Atlas Tools or ProBuilder may be a better option.
