The basic path: export from Blender, import into Roblox Studio
Roblox Studio does not open Blender files directly. You need to export your model from Blender as an FBX file, then bring that FBX into Roblox Studio using the import tool. The process takes about five minutes once you know the steps, but the export settings matter — get them wrong and your model arrives broken, textured incorrectly, or with parts missing.
This guide walks you through exporting from Blender the right way, then importing into Roblox Studio so your model is ready to use in your game.
Key Takeaways
- Export your Blender model as FBX format, not OBJ or DAE, because Roblox Studio handles FBX rigging and materials better.
- In Blender's export settings, turn on "Smoothing Groups" and "Apply Modifiers" so your model looks correct when it arrives in Roblox.
- Keep your FBX file under 20 MB and your model under 50,000 triangles, or Roblox Studio will reject it or it will lag in-game.
- In Roblox Studio, use the Model tab's Import button to bring in your FBX, then adjust the scale and position in the Properties panel.
Export your model from Blender as FBX
Open your finished model in Blender. Select all the objects you want to export by pressing A to select all, or click each object while holding Shift if you only want certain parts. If you have a rig (bones for animation), make sure the armature is also selected.
Go to File > Export As > Autodesk FBX (.fbx). A save dialog opens. Choose where to save the file and give it a clear name — something like "house_model.fbx" or "character_rig.fbx". Do not use spaces or special characters in the filename.
Before you click Export, the right panel shows export options. These settings control how your model behaves in Roblox Studio. Look for these checkboxes and make sure they are turned on:
- Apply Modifiers — this bakes any modifiers (like Subdivision Surface) into the geometry so they export correctly.
- Smoothing Groups — this preserves smooth shading so your model does not look faceted and blocky.
- Apply Scalings — set this to FBX All, so scale is handled properly on import.
- Forward — set to -Y Forward and Up to Z Up. This matches Roblox's coordinate system.
Leave everything else at default. Click Export FBX. Blender saves your file and you are done with the export.
Check your file size and triangle count before importing
Before you bring your model into Roblox, check two things: the file size and the polygon count. Roblox Studio will reject FBX files larger than 20 MB, and models with more than 50,000 triangles will cause lag in your game.
To check file size, right-click your FBX file in Windows Explorer or Finder and look at the file properties. If it is over 20 MB, your model has too much detail. Go back to Blender and delete unnecessary geometry, reduce texture resolution, or use the Decimate modifier to cut the triangle count in half.
To check triangle count in Blender, select all objects and look at the bottom right of the 3D viewport. You will see a line that says something like "Verts: 45,000 | Faces: 32,000". The face count is roughly your triangle count. If it is over 50,000, use the Decimate modifier: add a modifier to your object, choose Decimate, and drag the Ratio slider down until the face count drops below 50,000. Then export again.
Import the FBX into Roblox Studio
Open Roblox Studio and load the game where you want to place your model. In the top menu, click the Model tab. On the left side, you will see a button that says Import. Click it.
A file browser opens. Navigate to your FBX file and select it. Click Open. Roblox Studio reads the file and places your model in the center of your game world. If the model is huge or tiny, or rotated the wrong way, do not panic — you will fix that next.
Your model now appears in the Explorer panel on the left as a folder containing all its parts. You can rename this folder to something useful like "ImportedHouse" or "PlayerCharacter".
Adjust scale, position, and rotation in the Properties panel
Click on the model folder in the Explorer to select the whole import. The Properties panel on the right shows its current settings. Look for the Size field under the Transform section. This shows the model's dimensions in studs (Roblox's unit of measurement).
If your model is the wrong size, you have two options. The faster way is to change the Scale value in Properties. If your model is too big, try 0.5 (half size) or 0.1 (one-tenth size). If it is too small, try 2 or 5. Type the number and press Enter to see the change instantly.
To move your model, change the Position values (X, Y, Z) in Properties. Click in each field and type a new number. To rotate it, change the Rotation values. These are measured in degrees, so 90 rotates it a quarter turn.
If your model arrived upside down or sideways, you probably need to rotate it 90 degrees on one axis. Try rotating the X axis first, then Y, then Z until it looks right.
Fix materials and textures if they did not import
If your model arrived gray or with missing colors, the textures did not import. This happens because Roblox Studio does not automatically load image files from your computer — you have to add them separately.
In Blender, note the names of your materials. In Roblox Studio, click on each part of your model in the Explorer. In the Properties panel, find the Material dropdown and choose a material that matches what you want — Plastic, Metal, Neon, Wood, Concrete, Fabric, Slate, or Asphalt. This is a quick fix that makes your model look intentional even if the exact texture did not come through.
If you need the exact textures from Blender, you will have to upload the image files to Roblox separately and apply them by hand. That is a longer process — for now, choosing a material type from the dropdown is the fastest way to make your model look finished.
Common problems and how to fix them
The model does not appear in Roblox Studio. Check that the FBX file is under 20 MB. If it is larger, go back to Blender, delete unused objects, and export again. Also make sure you exported as FBX, not OBJ or DAE — Roblox Studio only imports FBX reliably.
Parts of the model are missing. This usually means you did not select all objects before exporting. Go back to Blender, press A to select everything, and export again. If you have a rig with an armature, make sure the armature is selected too.
The model looks blocky or faceted. In Blender's FBX export settings, make sure Smoothing Groups is turned on. If it is already on, your model may have hard edges in Blender itself. Select all faces in Blender (press A in Edit Mode), then press Shift + N to recalculate normals, and export again.
The model is rotated wrong in Roblox. In Blender's FBX export settings, check that Forward is set to -Y Forward and Up is set to Z Up. If you already exported, you can also just rotate it in Roblox Studio using the Rotation fields in Properties.
Frequently Asked Questions
Can I import a Blender file with animations or a rig?
Yes. Make sure your armature (rig) is selected before you export, and turn on Bake Animation in the FBX export settings if you want the animation to come with it. In Roblox Studio, the rig will import as a folder of parts connected by welds. You will need to set up animations separately in Roblox using the Animation Editor.
What if my FBX file is too large to import?
Roblox Studio rejects files over 20 MB. Go back to Blender and reduce detail: delete objects you do not need, use the Decimate modifier to cut triangles, or reduce texture resolution. Export again and check the file size before importing.
Do I need to use a specific version of Blender?
Blender 3.0 and newer export FBX reliably to Roblox Studio. If you are using an older version, update Blender first. You can download the latest version free from blender.org.
Can I edit the model after I import it into Roblox Studio?
You can move, rotate, and scale it, and change its material. You cannot edit the geometry itself in Roblox Studio. If you need to change the shape or add details, go back to Blender, make the changes, export a new FBX, and import it again.
Why does my model look different in Roblox than it did in Blender?
Roblox Studio uses different lighting and rendering than Blender. Materials also look different — Roblox has a smaller set of built-in materials. If the difference is dramatic, check that you exported with Smoothing Groups on, and try assigning a different material in Roblox Studio's Properties panel.
