Importing 3D models

Bring in GLB, glTF, and OBJ models — with Draco and meshopt compression supported out of the box.

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

FormatNotes
GLB / glTFThe recommended format. Draco and meshopt compression both work — the decoders are bundled, so compressed models load without any extra setup.
OBJSupported (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.
