GSprite

Desktop app15 GitHub stars

GSprite is a free, open-source Windows tool that turns a Grok Imagine video or photo into a pixel or smooth spritesheet.

Challenge

Game developers need a quick, efficient way to turn reference art into sprite sheet animations. Most workflows split that work across several tools, which slows down iteration when you just want to test a character or effect.

Work done

We released GSprite as a free, open-source Windows desktop pipeline. You upload a video or image from Grok Imagine, and the tool cuts the in-between frames, runs BiRefNet segmentation to remove the background on each frame, cleans halo artifacts, palletizes the result, and auto-resizes the sheet to 128x128 and 256x256. You can export a pixel look or a smoother sheet. The source is on GitHub under an MIT license.

Result

The tool is public for anyone to clone, fork, or use on a hobby project. The repository has collected GitHub stars from people who found it useful.
