Creating an item in Roblox starts with opening Studio, inserting a part, and then uploading it as an asset

An item in Roblox is any object you design and upload to the platform that players can wear, hold, or use in games. This could be a hat, a tool, a weapon, or a piece of furniture. To create one, you need Roblox Studio (the free building software), a Roblox account, and about 10 to 30 minutes depending on how detailed you want the item to be.

The basic process is: build the item in Studio using parts or models, test it to make sure it looks right, then upload it to the Roblox catalog so other creators can use it or so you can sell it. This guide walks you through each step.

Key Takeaways

  • Download Roblox Studio from the official Roblox website, create a new blank place, and insert parts to build your item shape.
  • Use the Model tab to group your parts together, then right-click and select "Export Selection" to save your item as a file.
  • Upload your item through the Create page on the Roblox website by selecting "Plugins" or "Models" and choosing your exported file.
  • After upload, your item appears in your inventory and can be added to games, sold on the catalog, or shared with other creators.
  • Items must follow Roblox's content policy: no real-world brand logos, no offensive imagery, and no items that copy existing catalog items too closely.

Download Studio and start a new place

Go to roblox.com, click the menu in the top right, and select "Create." On the Create page, click the blue "Start Creating" button. This takes you to a page where you can download Roblox Studio if you don't have it yet. The download is free and works on Windows and Mac.

Once Studio is installed and open, click "New" to start a blank place. Studio will load a default terrain and a baseplate. You can delete the baseplate by clicking it and pressing Delete — you won't need it for a single item.

Build your item using parts

In the left panel of Studio, click the "Model" tab. At the top of that panel, you'll see an "Insert Object" button (it looks like a plus sign). Click it and select "Part" to add a basic cube to your workspace. You can now shape this part by changing its size, color, and position.

To resize a part, click it, then in the right panel under "Properties," find "Size" and change the X, Y, and Z values. To move it, use the arrow keys or drag it with your mouse. To change its color, find "Color" in Properties and click the color box.

For more complex items, add multiple parts and position them next to each other. For example, a sword might be one long thin part for the blade and a shorter wider part for the handle. You can also insert cylinders, spheres, or wedges instead of cubes by clicking Insert Object and choosing a different shape.

Group your parts and check the scale

Once your item is built, select all the parts that make it up. Hold Ctrl (or Cmd on Mac) and click each part, or click and drag a box around all of them. Then right-click and select "Group" from the menu. This bundles them into a single object, which makes uploading easier.

Before you export, check the size. Roblox items should be roughly human-sized or smaller — a hat should fit on a player's head, a tool should fit in a player's hand. If your item is too big or too small, select the group, find "Size" in Properties, and adjust all three numbers equally to scale it up or down.

Export your item as a file

Right-click your grouped item and select "Export Selection." A window will open asking where to save the file. Choose a folder you can find later (like your Desktop), give the file a name, and click Save. Roblox will save it as a .rbxm file, which is the format the platform uses for items.

Do not close Studio yet — keep it open in case you need to make changes after you upload and test your item.

Upload your item through the Roblox website

Go to roblox.com/create and log in if you're not already. Click "Models" in the left menu. On the Models page, click the blue "Upload Model" button. A file browser will open. Navigate to where you saved your .rbxm file, select it, and click Open.

Roblox will ask you to name your item and write a description. Use a clear name like "Blue Wizard Hat" or "Iron Sword." The description can be a sentence or two explaining what the item is. Then click "Upload."

The upload usually takes a few seconds. Once it's done, you'll see your item in your Models inventory. From there, you can add it to any game you own, or you can configure it to sell on the Roblox catalog if you want other players to buy it.

Test your item in a game before selling

Before you make your item public or try to sell it, add it to a test game and see how it looks on a player character. Create a new blank place in Studio, then go to the Model tab and click "Insert Object" again. This time, select "Model from Roblox" and search for your item by name. Click it to insert it into the test game.

Run the game by clicking the green "Play" button at the top. Walk around and see if the item looks the way you intended. If it's the wrong size, color, or shape, go back to Studio, make changes to your original item, export it again, and re-upload it. You can overwrite the old version by uploading with the same name.

Understand Roblox content rules for items

Before you share or sell your item, make sure it follows Roblox's content policy. You cannot upload items that include real-world brand logos, trademarks, or copyrighted characters. You also cannot upload items that are nearly identical to items already in the Roblox catalog — Roblox will reject them as duplicates.

Avoid offensive imagery, hate symbols, or anything that could be used to harass other players. If your item breaks these rules, Roblox will remove it and may restrict your account. When in doubt, keep your item simple and original.

Frequently Asked Questions

Can I sell an item I created?

Yes. After you upload your item, go to your Models page, click your item, and select "Configure." Under "Sales," you can set a price in Robux (Roblox's in-game currency). Players can then buy it from the catalog. Roblox takes a percentage of the sale, and you keep the rest.

What if my item doesn't show up after I upload it?

Check that your .rbxm file exported correctly by opening it in Studio — right-click in the workspace and select "Insert Object," then "Model from File," and choose your .rbxm. If it opens and looks right, the upload should work. If the upload still fails, try exporting again and using a shorter file name with no special characters.

Can I edit an item after I upload it?

Yes. Make changes in Studio, export it again with the same name, and re-upload it. Roblox will overwrite the old version. Any games already using the old version will automatically update to the new one.

Do I need to pay to upload items?

No. Uploading items to Roblox is free. You only pay if you want to sell the item — and even then, you only pay a small percentage of the sale price to Roblox.

What file format does Roblox use for items?

.rbxm is the standard format. When you export from Studio, it automatically saves as .rbxm. Do not try to convert it to another format — Roblox will not recognize it.
