How to import a sprite sheet into Unity

1. Open your sprite (from Drive or the public gallery) and choose ZIP under Download Assets.
2. Unzip it. You need normalized_spritesheet.png, the frames/ folder and spritesheet.json.
3. Open README.txt: it lists the cell size (for example 128 x 128) and the grid (for example 4 columns x 4 rows). You'll type these numbers into the engine.

Pro Motion sheets store the exact playback rate in spritesheet.json (animations → fps). For other sheets the defaults are listed below.

1. Drag normalized_spritesheet.png into your Assets folder and select it.
2. In the Inspector set Texture Type to Sprite (2D and UI) and Sprite Mode to Multiple.
3. Set Pixels Per Unit to match the rest of your art (a common choice is the cell height, so one frame is one unit tall).
4. For pixel art set Filter Mode to Point (no filter) and Compression to None. Click Apply.

1. Click Open Sprite Editor, then Slice.
2. Choose Type: Grid By Cell Size and enter the cell width and height from README.txt. Leave offset and padding at 0.
3. Pick a Pivot: Center matches how frames are placed in their cells; use Bottom or a custom pivot for feet-on-ground characters.
4. Click Slice, then Apply. The sprites are named normalized_spritesheet_0, _1, … in reading order: left to right, top to bottom.

Item and icon sheets can have empty cells at the end of the grid. Leave Keep Empty Rects off and Unity skips them.

1. Select the sprites for one animation (for a walk cycle with 4 columns, _0–_3 is walk_down, _4–_7 walk_left, and so on) and drag them into the Scene or Hierarchy. Unity creates an Animation Clip and an Animator Controller.
2. Open the clip in the Animation window and set its sample rate to the FPS for the sheet (enable Show Sample Rate from the window's menu if the field is hidden).
3. Repeat for each row, then wire the clips into the Animator Controller.

Every frame is centered inside its cell, so a center pivot keeps the animation steady. If you want the pivot at the character's feet, set it once to the same point for every frame; because all cells are the same size, one value works for the whole sheet.

1. Import the frames/ folder instead, set every PNG to Sprite Mode: Single with the same pivot, and drag a run of frames into the scene to make a clip.

normalized_spritesheet.png

The sheet on a uniform grid: every cell is the same size, frames read left to right, top to bottom, on a transparent background.

frames/frame_001.png …

One PNG per frame, numbered from 001 in playback order, each the size of one cell.

spritesheet.json

Engine-friendly metadata: meta.size, a frames map with the x, y, w, h rectangle and duration (ms) of every frame, and for animated modes an animations map with frame names, fps and loop.

metadata.json and README.txt

Cell width and height, the grid (columns × rows), frame count and the original prompt.
