Before exporting a sprite sheet: size, order and anchors

Three things to settle before file size

A smaller sheet does not automatically make a better animation. Match cell size, playback order and the character’s reference point first. Without those details, the receiving person or application has to guess how the sheet should be used.

Example: four directions and eight poses

With 64×64px frames, four directions and eight motion frames produce 32 pictures. When Pixelizer can identify those groups, directions become rows and motion becomes columns: an 8×4 grid, or 512×256px. At 2× export, cells are 128×128px and the sheet is 1024×512px.

Directions are not motion frames. A still model rendered from four sides provides four views, not a walking animation. Select a motion clip and check it in one direction before expanding the view count.

Why cropping can introduce wobble

Trimming each frame differently can move the apparent foot or center position. Keep a consistent reference and include the complete jump or weapon movement. Sprite offers anchor alignment. Pixelizer’s sheet export places differently sized output frames into equal cells, centered horizontally and aligned at the bottom.

Match the file format to the task

• PNG sheet: use regions of one image as animation frames.
• GIF: review or share motion immediately.
• Pixelizer ZIP: receive individual PNGs for further layout or processing.

Pixelizer’s Sprite button and Ctrl+S export the complete result, regardless of the currently previewed frame. One downloaded PNG is expected; inspect the cells inside it.

Scale, filtering and padding are separate concerns

Export scale is integer enlargement of existing pixels. It does not create source detail. Smooth filtering or sampling near cell boundaries in another application can blur pixels or bleed neighboring cells. Review that application’s settings. Pixelizer’s automatic sheet export has no custom-padding or JSON coordinate-file option.

Include a short handoff note

Record cell size, columns and rows, occupied frame count, direction order, FPS and the ground or center anchor. Exclude any unused final cells from playback. If the sheet is too large, lower export scale or use ZIP to arrange frames elsewhere. See the sprite sheet guide for the complete process.
