Python tool for VFX artists to aid in different methods of texture flipbook atlasing.
Current methods are your default full RGB(A) flipbook tiled for VFX playback. There are currently 3 flavors of packing; Atlas, Super, and Stagger.
Super Packing and Stagger Packing both allow you to pack a minimum of 192 frames across the RGB channels or 256 frames across the RGBA channels. The way the images are packed into the channels is what makes them different.
This tool is built with Python 3.12 using the Pillow 10.2.0 package.
Under the bin folder, there are 3 bat files that will help you create the desired flipbook layout via the command line.
After the atlas_pack.bat filename, the first int arg is the rows, then the columns, and finally, the path to the images you want to pack.
atlas_pack.bat 6 6 "c:\path\to\images"
After the stagger_pack.bat filename, the only required argument is the path to the images you want to pack. Note that in order to pack this type of atlas, you must have either 192 or 256 images.
stagger_pack.bat "c:\path\to\images"
The final atlas is laid out as such:
- SourceImage 1-4 = TextureAtlas.001.RGBA
- SourceImage 5-8 = TextureAtlas.002.RGBA
- SourceImage 9-12 = TextureAtlas.003.RGBA
- SourceImage 13-16 = TextureAtlas.004.RGBA
After the super_pack.bat filename, the only required argument is the path to the images you want to pack. Note that in order to pack this type of atlas, you must have either 192 or 256 images.
super_pack .bat "c:\path\to\images"
The final atlas is laid out as such:
- Source Image 1-64 = TextureAtlas.R
- Source Image 65-128 = TextureAtlas.G
- Source Image 129-192 = TextureAtlas.B
- Source Image 193-256 = TextureAtlas.A
Under the examples module, you will find a few examples of how to call the flipbook packing methods from within your own Python scripts.
