Sprite sheet generator. - v1.2 First and last Showcase

This workflow provides a complete pipeline for transforming a single static sprite into a high-quality, game-ready animation sheet. It utilizes the Wan 2.2 I2V model to interpret a 480x480 input image and generate fluid, prompt-driven motion.

Key Features

Bridges a "First and Last Frame" reference to ensure consistent, loopable motion tailored for 2D combat or movement cycles.

Automatically identifies and removes green-screen backgrounds using a Chroma Key masking process, delivering clean alpha transparency without manual editing.

Features a dedicated ColorMatch subgraph that locks the generated animation frames to the original character's palette, preventing the "washed out" or green-tinted look common in raw AI video outputs.

Processed through ImageQuantize and Nearest-Exact downscaling to snap colors into a sharp 64x64 grid, preserving the "crunchy" retro look while eliminating sub-pixel blur.

Automatically extracts specific frames and stitches them into a perfectly aligned horizontal sprite sheet, ready for immediate import into engines like Unity, Godot, or GameMaker.
