Import OBJ into Roblox Studio, step by step

- 2Import into Roblox StudioHome tab › Import 3D, choose the .obj.
- 3Check scale and orientationRoblox Studio works in studs and is Y-up. OBJ files are unitless, so the size depends on what the exporter assumed.
- 4Check materials and animationOBJ carries basic materials in a separate .mtl file, and no animation. Look at the model under a neutral light before you build on it.
What comes through

Things to watch for
- OBJ is fine for static props; textures can be assigned in the importer.
- Roblox limits triangles per mesh, so simplify dense scans and AI models before importing.
