How to check transparent character frames against game backgrounds before export

Transparent PNG frames can look clean on a checkerboard yet show halos or dark fringes once placed in a game scene. The article recommends testing each frame on dark, light, and scene-matched backgrounds, with attention to outlines, gaps between limbs, and small accessories. Reviewers should inspect at actual display size first, then zoom in, and check the intended camera zoom and both calm and busy backgrounds. Pixel art calls for nearest-neighbor, integer scaling, while other 2D styles should keep their intended antialiasing and be judged at the planned display scale. The piece also advises previewing the frame sequence at planned timing and testing a small sequence in the target engine to verify filtering and pivot, with a disclosure that it was prepared with an AI assistant for MotifDeck, which offers a paid download unlock.
