What you're actually doing when you "read" a voxel

Roblox Studio doesn't have a single "read voxel" button. What you're doing is exporting a model you built or imported into Studio so you can use it elsewhere — either in a different Roblox game, in another 3D program, or as a file on your computer. The process depends on what you want to do with the voxel after you export it.

If you built the voxel in Studio yourself, you save it as a model file within Roblox. If you want to move it to another program like Blender or use it outside Roblox entirely, you'll export it as a mesh file. Both paths start in Studio, but they go in different directions.

Key Takeaways

  • Saving a voxel model within Roblox Studio means right-clicking the model, selecting "Save to Roblox", and choosing whether to save it as a new model or update an existing one.
  • Exporting a voxel to use in other 3D programs requires a third-party tool like Roblox Model to OBJ Converter, since Studio doesn't have a built-in export function.
  • You need to own the model or have permission from the creator before you can save or export it — copying someone else's work without permission violates Roblox's terms.
  • Exported mesh files are usually in OBJ or FBX format, which work in Blender, Maya, and other 3D software, but lose some Roblox-specific properties like scripts and welds.

Saving a voxel model within Roblox Studio

If you built a voxel model in Studio and want to keep it for use in other Roblox games you create, save it as a model. Right-click the voxel or group of parts in the Explorer window on the left side of Studio. A menu appears — select "Save to Roblox".

A dialog box opens asking whether you want to create a new model or update an existing one. If this is the first time saving it, choose "Create New Model". Give it a clear name — something like "Stone Tower Voxel" or "Crystal Formation" — so you can find it later. Click "Save".

The model now appears in your Roblox inventory under "Models". You can insert it into any other game you're building by going to the Toolbox in Studio, clicking the Models tab, and searching for the name you gave it. This is the fastest way to reuse voxels across multiple projects.

Exporting a voxel to use outside Roblox

Studio itself doesn't have a built-in export function for voxels or models. To get a voxel out of Roblox and into another program like Blender, you need a converter tool. The most common option is Roblox Model to OBJ Converter, which you can find on GitHub or through Roblox community sites.

read the converter tool to your computer. Open Studio and select the voxel or model you want to export. Copy it (Ctrl+C on Windows, Cmd+C on Mac). Open the converter tool and paste the model data into it. The tool will generate an OBJ file — a standard 3D format that Blender, Maya, and most other 3D software can open.

Save the OBJ file to a folder on your computer. You can now open it in any 3D program. Keep in mind that when you export, you lose Roblox-specific features like scripts, welds, and custom properties — you're left with just the geometry and basic materials.

What you need before you can save or export

You must own the voxel model or have explicit permission from the creator. If you built it yourself in Studio, you own it. If you imported a model from the Roblox catalog or downloaded one from a creator, check the model's description or contact the creator to ask whether you can export or redistribute it.

Many voxel models on Roblox are free to use in your own games but not free to export or resell. Trying to save or export someone else's work without permission violates Roblox's terms of service and can result in your account being restricted. When in doubt, ask the creator first.

Storing and organizing exported voxel files

When you export voxels as OBJ or FBX files, create a dedicated folder on your computer to keep them organized. Name the folder something clear like "Roblox Voxels" or "3D Models". Inside, create subfolders by type — "Terrain", "Buildings", "Props" — so you can find what you need quickly.

Keep the original Studio file as well as the exported version. The Studio file lets you make changes and re-export if you need to adjust the model. The exported file is what you use in other programs. Backing up both means you won't lose work if something goes wrong.

Common problems and how to fix them

If "Save to Roblox" is grayed out, you probably have parts selected that aren't grouped together. Select all the parts that make up your voxel, right-click, and choose "Group" first. Then try saving again.

If the converter tool won't read your model, make sure you're copying the entire model from the Explorer, not just individual parts. Select the top-level folder or group that contains all your voxel parts, then copy and paste into the converter.

If the exported OBJ file looks wrong in Blender — missing textures, broken geometry, or pieces in the wrong place — this is normal. Roblox and Blender handle scale and materials differently. You may need to rescale the model in Blender and reapply textures by hand.

Frequently Asked Questions

Can I read voxels that other people made in Roblox?

You can insert other people's models into your own Studio project if they're shared publicly, but you cannot export them without permission. If a creator has marked their model as exportable, the converter tool will work. Otherwise, you're limited to using it within Roblox games.

What's the difference between OBJ and FBX format?

OBJ is simpler and works in almost every 3D program, but it doesn't store animations or complex material data. FBX is more advanced and preserves more information, but not all programs support it equally. For voxels, OBJ usually works fine.

Do I lose anything when I export a voxel from Studio?

Yes — scripts, welds, custom properties, and Roblox-specific materials are lost. You keep the shape and basic colors, but you'll need to rebuild any moving parts or special behavior in your new program.

Can I edit an exported voxel in Blender and bring it back to Roblox?

Yes. Edit the OBJ file in Blender, export it as OBJ again, then import it back into Studio using the Mesh Import tool. You'll need to reapply textures and set up any scripts or physics properties from scratch.

Is there a size limit for voxels I can export?

Roblox has limits on model complexity and file size, but they're generous for most voxel projects. If your model has thousands of individual parts, it may slow down Studio or fail to export. Combining parts or using a single mesh instead of many small cubes helps.
