and save the shot
UmaStudio loads characters straight from your installed game. Pick a pose and an expression, give her a prop and a background, then save a PNG or a video.
Free and open source. For Windows, with the Steam version of the game.
Pick from every character your game has downloaded, in her own outfits or the shared ones: uniforms, tracksuits and the rest.
Their chibi versions too, with the game's chibi faces and motions, and over 800 background Umas from races and events, coloured the way the game colours them.
Everyday motions, victory poses, cut-ins, dances, training and story scenes, plus each character's own. Search them in plain English: arms crossed, waving, phone.
Pause anywhere and that frame is your pose. Hair and clothes move with the game's own physics.
Over 500 of the game's hand props, most with their own grip so her fingers close around them. Or use your own picture: as a card, on a box, or on one of the game's props.
Over 1,000 of the game's story backgrounds, wide and vertical, or a picture of your own. Zoom, move and blur it until it fits.
Or keep it transparent, white or green for editing later.
Every expression in the game, or set eyebrows, eyes, mouth and iris one by one.
Turn on Look at camera and her eyes, or eyes and head, follow you while she moves.
PNGs up to 4K, transparent if you like. Videos at 30 or 60 fps, rendered frame by frame so they come out smooth on any PC. The clip on the left was recorded in UmaStudio.
Click a joint and turn it with the rings, on top of any game pose. Arms, head, legs, ears, fingers. Save the poses you like and load them onto other motions.
Then take her to Blender: her mesh, skeleton, textures and props as one .glb, in the pose or with the whole motion baked in, physics included.
UmaViewer is the long-running asset viewer for the game. UmaStudio is built for one job: making pictures and videos of an Uma. Here is where that shows.
| UmaStudio | UmaViewer | |
|---|---|---|
| Props in her hands | Over 500 game props, placed in her hand with the game's own grips. Your pictures as cards, boxes or on a prop. | Props load as separate objects. Holding them is an open request. |
| Video | MP4, WebM and MOV, the last two with transparency, at up to 60 fps. Every frame is rendered on its own. | GIF and image sequences. |
| Setup | Finds the Steam install by itself. Nothing to point it at. | Tries to find the data folder. If that fails, you set it in the settings. |
| Game updates | Reads the database key from your own install, so an update that changes it does not need a new UmaStudio. | Ships the key in its code. After the July 2026 Global update it needed a new build to read the data again (#218). |
| Finding a pose | Over 4,000 poses, grouped and searchable in plain English, plus her own. | Animation lists per category. |
UmaViewer still does more in a few places: concerts with the song, lyrics and stage, MMD export (PMX and VMD), and the JP and KR clients. If you need those, use it.
UmaStudio reads the game files already on your PC. Nothing is uploaded and there is no account.
