Get Sheet Done is an addon for Blender that generates grid-based spritesheets directly inside the application. It can create sheets from a set of images or when rendering an animation, and it works without any external software beyond Blender and the addon itself. Spritesheets are mostly used in popular game engines as animation sheets.
Because it relies only on Blender, the addon runs on any platform and works with any render engine or image file format that Blender can use. It suits situations where you need to combine sprites into a spritesheet or simply merge a couple of images quickly within Blender.
The addon is supplied with Documentation and an FAQ. Version 1.5.0 adds support for the Blender 5.0+ Python API changes and was tested with Blender 5.0.1 Stable, with earlier releases tracking Blender 4.4+, 4.0+, 2.90+, 2.81+ and 2.80 API changes. Installation is done by navigating to the .zip file without unpacking it; when updating, remove the old version first and restart Blender.
