Roblox Studio 3D file formats: what opens and how
Roblox Studio is the editor for building Roblox experiences; custom meshes come in through its 3D Importer. It opens 4 of the 9 common 3D formats below without conversion; for the rest, convert to OBJ first.

Which format to choose
GLB and FBX are the most dependable choice for Roblox Studio. The 3D Importer reads glTF, so a GLB brings its mesh and PBR textures in one file. If a model arrives as STL, PLY, 3MF, convert it to OBJ so materials survive the trip.
Units and orientation
Roblox Studio works in studs and is Y-up. Most problems after an import, such as a model that is invisible, enormous or lying on its side, come from a mismatch with the exporting app rather than a broken file.
- Roblox limits triangles per mesh, so simplify dense scans and AI models before importing.
- The 3D Importer preview shows warnings for scale, missing textures and too many triangles; fix them before you click Import.
