Importing 3D models
Bring in GLB, glTF, and OBJ models — with Draco and meshopt compression supported out of the box.
Open in the interactive manual →The interactive version has full-text search, a table of contents, and light/dark themes.
3dCMS imports standard 3D model formats so you can drop in furniture, characters, props, scanned objects — anything you've made or downloaded.
How to import
- File ▸ Import a GLB/GLTF model — it's uploaded to your Asset Library and referenced by URL, which keeps your scene file small and lets repeated copies render efficiently.
- Or click any model in the Asset Library to place it.
Supported formats
| Format | Notes |
|---|---|
| GLB / glTF | The recommended format. Draco and meshopt compression both work — the decoders are bundled, so compressed models load without any extra setup. |
| OBJ | Supported (with its MTL materials). |
Two gotchas with imported models
- KTX2 / Basis textures aren't supported yet — re-export the GLB with PNG/JPEG textures if you hit that message.
- Imported meshes can't be poly-edited. You can move, scale, recolor (via Tint), and decimate them, but not edit their vertices.
No model? Generate one.
If you don't have a model handy, the AI Assistant can generate a textured 3D model from a text prompt and place it for you.
