Can Godot Open STL Files? How to Import Them
Godot is a free, open-source game engine whose recommended 3D format is glTF; files copied into the project folder are imported automatically.
Short answer · Convert first
Not directly. Godot doesn't import STL, so convert the file to GLB first and import the GLB.

- 1Check the fileFind out what units the part was designed in. Almost every printable STL is in millimetres, but the file itself doesn't say.
- 2Convert STL to GLBDrop the file into our STL to GLB converter. It runs in your browser, so the model never leaves your computer.
- 3Import into GodotCopy the .glb into the project folder; it appears in the FileSystem dock and can be dragged into a scene.
- 4Check scale and orientationGodot works in metres and is Y-up. STL files are unitless (slicers assume millimetres), so the size depends on what the exporter assumed.
- 5Check materials and animationSTL carries no colour or materials, and no animation. Look at the model under a neutral light before you build on it.
What comes through
| Shape | Yes, always. |
| Colours and materials | Yes: PBR materials and embedded textures. |
| Textures | STL doesn't store texture images. |
| Animation | No: GLB has no animation. |
Things to watch for
- Godot doesn't treat STL as a standard 3D scene format. Converting to GLB gives you a mesh that imports cleanly.
- Double-click an imported file in the FileSystem dock to open the Advanced Import Settings, where you can set physics, materials and animation options.
Questions
- Does Godot support STL files?
- Not directly. Godot doesn't import STL, so convert the file to GLB first and import the GLB.
- Why is my STL model the wrong size in Godot?
- STL files are unitless (slicers assume millimetres), while Godot works in metres. Scale the model after importing, then apply the scale before you continue.
- What is the best 3D format for Godot?
- GLB and FBX are the most reliable choice for Godot. If you have a choice when exporting, pick GLB over STL.
