What a mesh ID is and where to find one

A mesh ID is a reference number that points to a 3D model stored on Roblox's servers. When you use a mesh ID in Roblox Studio, you are not uploading a new file — you are telling Studio to display a model that already exists in Roblox's library. Mesh IDs look like numbers preceded by "rbxassetid://", for example: rbxassetid://1234567890.

You can find mesh IDs in several places. The Roblox catalog (roblox.com/catalog) shows thousands of free and paid models; when you click on a model, the ID appears in the URL or in the item details. Community sites like the Roblox Developer Forum and asset libraries maintained by builders also list mesh IDs. Some creators share IDs directly in their games or on social media. If you have uploaded your own mesh to Roblox, you can find its ID in your Creator Dashboard under Creations > Models.

Before you import, make sure you have permission to use the mesh. Free models in the catalog are yours to use. Paid models require you to own them first. Models created by other users belong to them — using them without permission can result in your game being taken down.

Key Takeaways

  • A mesh ID is a number that points to a 3D model already stored on Roblox's servers, formatted as rbxassetid:// followed by digits.
  • You insert a mesh into Studio by creating a MeshPart, pasting the ID into the TextureID property, and adjusting size and position as needed.
  • Free models from the Roblox catalog can be used in your games, but paid models and user-created models require ownership or permission.
  • If a mesh ID does not load, check that you copied the full number correctly and that the model has not been deleted or made private by its creator.

Creating a MeshPart and inserting the mesh ID

Open your game in Roblox Studio. In the Model tab at the top, click Insert, then scroll down and select MeshPart. A new part will appear in your workspace — it will look like a gray cube at first. This is the container that will hold your mesh.

With the MeshPart selected, look at the Properties panel on the right side of the screen. Scroll down until you find the property called TextureID (not MeshId — that is different). Click in the TextureID field and paste your mesh ID. Make sure to include the full "rbxassetid://" prefix. Press Enter. The mesh should load within a few seconds and replace the gray cube with your 3D model.

If the mesh appears but looks wrong — too small, too large, or rotated oddly — you can adjust it. The Size property controls scale. The Rotation property (under Transform) controls angle. Experiment with these values until the mesh looks the way you want it in your game.

Troubleshooting meshes that do not load

If you paste a mesh ID and nothing happens, or the part stays gray, the most common cause is a typo in the ID number. Copy the ID again from your source and paste it carefully into the TextureID field. Make sure there are no extra spaces before or after the number.

The second most common cause is that the mesh has been deleted or made private by its creator. If you found the ID on a community site or in an old forum post, the model may no longer exist. Try searching the Roblox catalog for a similar model and use that ID instead.

If you own the mesh but it still will not load, check your Creator Dashboard to confirm the mesh is public, not private. Private models can only be used by you in Studio, not in published games. If the mesh is public and the ID is correct, try removing the MeshPart and creating a new one, then pasting the ID again.

The difference between TextureID and MeshId

Roblox Studio has two similar properties that confuse many builders. MeshId is the shape of the 3D model — the actual geometry. TextureID is the image wrapped around that shape. When you import a mesh from the catalog, you are usually pasting the ID into TextureID because the catalog models include both the shape and the texture as one package.

If you have a mesh file you created in Blender or another 3D program, you would upload it to Roblox first, which gives you a MeshId. Then you could explore a separate texture to it using TextureID. For most builders starting out, you will use TextureID with catalog models and not need to worry about MeshId.

Using mesh IDs in scripts and game logic

Once you have a mesh in your game, you can change it with a script. This is useful if you want a part to swap between different models when something happens — for example, a sword that changes appearance when upgraded. Open the Script editor and use code like this:

local part = script.Parent part.TextureID = "rbxassetid://1234567890"

Replace 1234567890 with the actual mesh ID. When the script runs, the part's mesh will change to the new ID. You can trigger this with events like touching, clicking, or collecting an item. This technique lets you create dynamic visual changes without uploading new parts to your game.

Performance and mesh count considerations

Each mesh you add to your game uses memory and processing power. If you add hundreds of detailed meshes to a single area, players on slower devices may experience lag or stuttering. Test your game on different devices to see how many meshes your game can handle smoothly.

If performance becomes a problem, you have a few options. You can reduce the number of meshes in areas where players spend time. You can use simpler meshes with fewer polygons (the catalog usually lists polygon count). You can also use LOD (level of detail) techniques, where meshes are swapped for simpler versions when the player is far away. For most small games, mesh count is not a concern — focus on building first and optimizing only if you notice slowdown.

Frequently Asked Questions

Can I use a mesh ID from a game I found online?

Not directly — mesh IDs are tied to the account that uploaded them. If you find a mesh ID in someone else's game, it may not work in your game if that creator made it private. Your best option is to search the Roblox catalog for a similar public mesh, or ask the creator for permission and the ID of a public version.

What happens if I use a mesh ID and the creator deletes it later?

The mesh will disappear from your game and show as a gray part. Your game will still work, but players will see the placeholder instead of the model. To fix it, replace the ID with a different mesh or remove the part entirely.

Do I need to upload a mesh file to use a mesh ID?

No. If you are using a mesh ID from the Roblox catalog or from another creator, the mesh is already uploaded. You only upload a mesh file if you created it yourself in Blender or another 3D program and want to use it in your games.

Can I change a mesh ID while my game is running?

Yes. Using a script, you can change the TextureID property at any time. This happens when ready in the game, so players will see the mesh swap when ready when the script runs.

Why does my mesh look stretched or distorted?

This usually happens when the Size property of the MeshPart does not match the mesh's original proportions. Try adjusting the Size values (X, Y, Z) to different ratios until the mesh looks correct. You can also check if the mesh itself has unusual proportions by viewing it in the catalog first.
