Export accessories to Roblox

Accessories export only as .lowpoly files. The file has the shape and its colors and paint, made for the Ünflat Studio plugin to read. The file has no Roblox IDs. On the first build, you choose to upload the mesh and picture to your Roblox account (free) or skip it; without the upload, the build lasts until Studio closes.

1. Download the .lowpoly

Go to Share › For a game: Roblox, .glb, sprites… › Roblox, then select Accessory under On an avatar. In the Avatar accessory (.lowpoly) section, select the slot (Hat, Hair, Face, Neck, Shoulder, Front, Back, or Waist) and body type (Classic, Normal, or Slender). The check panel points out problems; they do not block the download. Its first line gives the piece’s size and the slot’s limit (e.g., … studs, 564 triangles. The Classic Hat slot fits up to … studs.). Select Check the size to see the piece on a Roblox mannequin and set its size; the line then reads Sized on the mannequin. A piece bigger than its slot still works in your own games, but Roblox’s Marketplace refuses it (the Accessory Fitting Tool warns that it will fail UGC Validation). Select Download .lowpoly. The file name is the fig’s name and the slot (e.g., Robot_hat.lowpoly). For all the checks and settings, see Roblox accessories .

The page ends with a Save to Roblox section: Optional: Save to Roblox… in the Studio plugin uploads the model to your Roblox account. It also points to the plugin’s checklist for selling an accessory on the Marketplace. The app has no upload for models.

2. Build it in Studio

Move the file to a computer. See Get the file to a computer . In Roblox Studio, go to the Plugins tab, select Import Model on the Ünflat toolbar. In the panel, select the Make dropdown, then Accessory, then Import a model…, and select the file. The plugin reads the file and builds a flat-shaded, painted Accessory that fits the chosen slot: one that doesn’t move is a single MeshPart (its Handle) with the slot’s Attachment placed where it meets the body.

3. Fit it with the Accessory Fitting Tool

Open Studio’s Accessory Fitting Tool. Select the built model and preview its position on a test rig. The plugin already placed the slot’s Attachment; use the tool to move it. The accessory is ready to test and use in your own projects for free. With the plugin’s uploads on, it saves with the place; without them, it lasts until Studio closes.

File contents

• Skins: With two or more skins, every skin goes into the file (skins that are not uploaded swap in Studio only). The plugin adds a lowpoly_skin attribute on the built model. Select a skin in the Skin dropdown of the plugin’s Details card, or change this attribute in the Properties panel. A selected skin stays on when you press Play.
• Outfits: With one or more outfits, all the clothes go into the file, with a lowpoly_outfit attribute to select one. A fig wearing Nothing comes in bare, with Nothing first in the list. Selecting an outfit also switches to its skin, if one is pinned.
• Animated skin: The skin’s frames go into the file. The plugin plays them at the animated skin’s Frame rate.
• Moves: The fig’s moves go into the file. The plugin plays them at the same Frame rate and easing when you press Play in Studio. Idle moves (e.g., Sway, Bounce) are saved as endless loops. Part group moves go in as a separate loop for each member; parts with their own moves keep those instead of the group’s. A loop on Everything goes in on each part attached to nothing that has no move of its own and no group move. Move sets go in by their kind: step sets go in as a list of frames and keep their ending; older sets (listed as Everything it did) play each part’s own moves as before. The lowpoly_moveset attribute names the set that plays. See The Roblox Studio plugin .
• Saved poses: Poses go into the file, with a lowpoly_pose attribute. Change the attribute to switch pose. Part group poses apply to each member part, rotated about the group’s pivot (plugin 2026-09-24e or later, with a file exported since).

Size changes in moves or poses do not reach Roblox: the plugin never resizes parts, so they keep their exported size.

Cost

Putting accessories on test rigs and using them in your own Studio projects is free. Wearing your own upload on your avatar costs an 80 Robux fee. Putting it on the Marketplace needs two-step verification and a Plus or Premium membership. The Marketplace accepts only accessories that don’t move; one that moves is for your own games. The plugin’s Accessory page shows a checklist with Save to Roblox…. See Roblox: upload your accessory for the steps.
