Roblox Studio is the editor for building Roblox experiences; custom meshes come in through its 3D Importer.
Short answer · Built in

Import GLB into Roblox Studio, step by step
- 1Check the fileA GLB is self-contained: geometry, materials and textures are inside the one file, so there is nothing else to copy.
- 2Import into Roblox StudioHome tab › Import 3D, choose the .glb.
- 3Check scale and orientationRoblox Studio works in studs and is Y-up. GLB files are metres by convention, so they normally arrive at the right size.
- 4Check materials and animationGLB carries PBR materials and embedded textures and can carry animation. Look at the model under a neutral light before you build on it.

| Colours and materials | Yes: PBR materials and embedded textures. |

Things to watch for
- The 3D Importer reads glTF, so a GLB brings its mesh and PBR textures in one file.
- Roblox limits triangles per mesh, so simplify dense scans and AI models before importing.
