# AI Sprite Sheet Generator > Yes — partly. An AI sprite sheet generator draws a game character and lays out several animation frames — idle, walk, attack — on one grid image. On Kenerate AI you design the character first, then attach it as a reference in Nano Banana 2.1 (up to 14 references, 21 credits at 1K) and ask for, say, an 8-frame walk cycle on a 4×2 grid. What AI doesn't do: guarantee equal cells, keep every frame perfectly on-model, put pixels on a true grid or export an atlas file — so you check the frames, tidy them in a pixel editor and slice the sheet in your engine.

Design the character — In /app/image, describe the character full body in side view on a flat background. Sign in free for 25 starter credits. 2. Make the frame grid — Attach the character as a reference in Nano Banana 2.1 and ask for one animation — “8-frame walk cycle on a 4×2 grid, equal cells, same character” — in a 2:1 or 1:1 ratio. 3. Clean up the pixels — Downscale the sheet with nearest-neighbour to your cell size, reduce the palette, fix stray pixels and line up the feet in a pixel editor. Remove the background if it isn't flat. 4. Slice it in your engine — In Godot use “Add frames from a Sprite Sheet” with the column and row counts; in Unity slice with Grid By Cell Count or Cell Size. Set the frame rate and test it in the game. ## In depth ### What AI does well — and what you still do by hand Being clear about this saves hours: - Does well: character design, a readable silhouette, poses for key frames, a whole cycle roughed out on one grid. - Mostly right: the same character across frames when you attach a reference and change one thing at a time. - Not reliable: equal cell sizes, a fixed ground line, smooth in-between frames, true one-pixel grids. - Not done at all: atlas or JSON metadata, frame timing, engine import — that's your editor and engine. ### Sprite sheet prompts you can copy Attach your character as a reference for every one of these: - Walk cycle: “8-frame walk cycle of this exact character, side view facing right, 4 columns × 2 rows, equal cells, feet on the same ground line, same colours and proportions, 16-bit pixel art, flat magenta background.” - Idle: “4-frame idle animation of this character breathing, side view, one row of 4 equal cells, subtle motion only, limited palette, white background.” - Attack: “6-frame sword attack of this character, side view facing right, 3 columns × 2 rows, wind-up, swing, follow-through, same sword in every frame, pixel art.” - Top-down: “Top-down three-quarter view walking sheet of this character, 4 rows (down, left, right, up) × 4 frames, equal cells, 16-colour palette, flat background.” - Item set: “A sheet of 12 fantasy RPG item icons — potions, keys, swords, shields — 4 × 3 grid, equal cells, 32×32 pixel-art style, white background.” ### How many frames do you need? Fewer than you think. A common starting point is 2–4 frames for an idle, 4–8 for a walk or run, and 3–6 for an attack. Summer Engine's generator uses 8 frames on a 4×2 grid per motion; a four-direction walk is often 4 frames per direction. Ask for the frame count you'll actually use. More frames per image means smaller cells and more drift between them. ### Pixel cleanup checklist Before the sheet goes into the game: - Downscale the whole sheet at once with nearest-neighbour, by a whole-number factor, to the cell size you need. - Reduce to a fixed palette so every frame uses the same colours. - Line up the feet on one ground line and the body centre in the same spot in each cell. - Remove stray and half-transparent edge pixels. - Play the row at a slow frame rate, then at game speed, and redraw the one frame that pops. - Write down cell width and height, columns, rows and frame rate next to the file. ### Slicing the sheet in an engine Godot 4: create a SpriteFrames resource for an AnimatedSprite2D, choose “Add frames from a Sprite Sheet”, set the horizontal and vertical frame counts and pick the frames — or set Hframes and Vframes on a Sprite2D. Unity: set the texture's Sprite Mode to Multiple, open the Sprite Editor and slice with Grid By Cell Count (columns and rows) or Grid By Cell Size (pixel width and height), using Offset and Padding if the grid doesn't start at the corner. ## FAQ Q: Can AI make a sprite sheet? A: It can draw one: a character and several animation frames laid out on a grid in a single image. It can't yet guarantee that every cell is the same size, that the character never changes between frames, or that the pixels sit on a real pixel grid. Treat the output as a strong first pass that you check, tidy and slice yourself. Q: How do I keep the same character in every frame? A: Generate the character once, save it, and attach it as a reference every time. In Nano Banana 2.1 write what must stay — “same character, same colours, same sword, same proportions” — and only the motion that changes. One animation per image works better than idle, walk and attack in one sheet. Reject sheets where the silhouette or a prop changes. Q: What grid and ratio should I ask for? A: Match the ratio to the grid: 2:1 for 4 columns × 2 rows (an 8-frame cycle), 1:1 for 4 × 4 (four directions × four frames), 4:1 for a single row of four frames. GPT Image 2.5 Sunburst offers 2:1 and 3:1; Nano Banana 2.1 offers 16:9, 4:1 and 8:1. Write “equal cells” and the counts in the prompt. Q: Is the output real pixel art? A: Not quite. Models draw a pixel-art look at about 1K–2K, so a “pixel” is several real pixels and edges may be soft. Downscale the sheet with nearest-neighbour to your cell size (32 or 64 pixels, say), reduce it to your palette and fix stray pixels in a pixel editor. Recraft 20B's Pixel art style and the image-to-pixel-art tool get you closer. Q: Does Kenerate export a sprite atlas or JSON? A: No. You download a PNG or JPEG of the grid. There's no atlas, JSON metadata or frame slicer in the app, so you set the cell size and frame order in your engine or editor. Godot's “Add frames from a Sprite Sheet” and Unity's Sprite Editor grid slicing both take a plain grid image. Q: Can it make top-down sprites in four directions? A: Yes, with some work. Make the character first, then use the Camera Angle turnaround to get front, right, back and left views of the same design. Use those as references for a 4 × 4 sheet — one row per direction, four walking frames each — in a top-down three-quarter view. Q: Can I get a transparent background? A: Ask for a flat background colour that isn't in the character, such as pure magenta, and key it out in your editor — that keeps hard pixel edges. Or use Remove BG in Edit Studio (Kenerate Cutout, 1.2 credits) and then clean the edge pixels, since an AI cutout can leave soft or missing edge pixels on small sprites. Q: Can I animate a sprite with video instead? A: You can animate the character with image-to-video and then pull frames out of the clip with a local tool such as ffmpeg. It gives smooth motion, but the frames need the same pixel cleanup and the camera must stay still. Video needs a one-time credit pack. Q: Is the AI sprite sheet generator free? A: Free to start. A new Kenerate account gets 25 credits on sign-up and Qwen Image 3.0 is on the free plan. Nano Banana 2.1 costs 21 credits per sheet at 1K and Recraft 20B 6.6 per image. After that, credits come in one-time packs with no subscription. Downloads carry no watermark. ## Related pages - Image to pixel art: https://kenerateai.com/image-to-pixel-art - Fakemon generator: https://kenerateai.com/fakemon-generator - Character turnaround AI: https://kenerateai.com/character-turnaround-ai - AI game asset generator: https://kenerateai.com/game-asset-generator-ai - Remove white background: https://kenerateai.com/remove-white-background - 2D art generator: https://kenerateai.com/2d-art-generator ## Sources - Kenerate Image Studio: https://kenerateai.com/app/image - Godot Engine docs — 2D sprite animation: https://docs.godotengine.org/en/stable/tutorials/2d/2d_sprite_animation.html - Unity Manual — Sprite Editor automatic and grid slicing: https://docs.unity3d.com/2022.3/Documentation/Manual/sprite-automatic-slicing.html
