Sint Turntable turns one concept image into a full 360° turntable with MiniMax H3. Characters, props and creatures spin once in front of a locked camera, and the workflow pulls 8 direction frames, 45° apart, ready for a model sheet, a sprite rig or a portfolio spin.
It is built on the official ComfyUI image-to-video template for H3, so the nodes and model files are the ones you already have. What changes is the prompt: a timed spin that tells H3 where the subject faces at every quarter, and what its back looks like.
How to use
- Your concept: one subject, centered, with room around it, on a flat mid-grey background. Characters in a relaxed A-pose.
- Swap the subject in the prompt and rewrite the back line (at 2.5 seconds) with what the back really shows. That line keeps the back coherent.
- Name what must not move in the rigid line: cloak, hair, ears, hanging props.
- Keep the clock and the 5 s duration. The 8 frames are picked for 124 frames at 24 fps.
- Tested on: 768x768 (768x1344 for tall characters), 20 steps, res_multistep, seed 42, turbo off.
What you get
- A 5 s turntable that closes the loop: the last frame lands back on the first, so it plays as a seamless spin.
- 8 PNG frames in rotation order, saved next to the video.
- A back that follows your description and the front: straps, quivers, backpacks and hinges stay on the right side.
- Camera, height and scale hold still for the whole spin.
Known quirks
- The spin eases in and out. Profiles and back land on the quarter marks; the 45° and 315° frames sit a bit closer to the front. Need exact diagonals? Pick them from the video.
- Some subjects spin unevenly, fast in one half and slow in the other. Reroll the seed.
- Swinging props like capes and chains can drift. Name them in the rigid line.
Third piece of the Sint gamedev kit, after Sint Albedo for tileable textures and Sint Pixel for pixel sprites. More tools for people who make games are on the way. If that is your world too, follow along.
