Tools

export_loading_frames.py

Renders the loading screen animation and exports every unique frame as both PNG files and a NumPy array.

Usage

uv run export_loading_frames.py [--out-dir <directory>]

Argument	Default	Description
--out-dir	frames/	Directory to write output files into

Outputs

File	Description
frames/frame_XXXX.png	One PNG per unique frame, zero-padded index
frames/frames.npy	NumPy array of shape (N, H, W), dtype bool

Consecutive duplicate frames are collapsed so only visually distinct frames are exported. The script prints the total number of frames rendered and the number of unique frames kept.
