Scene Building

The toolbar below the 3D viewport and above the timeline provides features for adding geometry and uploading scenes. Place a 3D environment in the scene to generate motions and draw trajectories based on actual scene geometry.

Building with Geometry

You can create simple geometry such as cubes, cylinders, cones, spheres, capsules, and planes to easily build simple geometric scenes.

Custom Scenes

Custom Scenes includes an asset library and an upload feature. You can find simple scene assets in the library or upload your own 3D scene assets.

Click "Upload Scene (.glb, .obj)" in the panel, then select a file from your computer.

• Only .glb and .obj formats are supported. Other formats, including plain .gltf, are rejected with an error message.
• A small loading indicator appears next to the filename while the file is being parsed.
• Once loaded, the scene is automatically placed on the ground plane (its lowest point is aligned to y = 0), matching the ground used by MOASIS-generated motions. The scene's original X/Z layout is preserved, so multiple imported scenes that share the same coordinate origin will align with each other.

Scene Assets

You can view, hide, and delete geometry from Scene Assets on the right:

• An 👁️ icon to show or hide the scene without removing it.
• A × (Remove Scene) button to delete it entirely.

After clicking geometry or a scene, a properties panel appears in the asset panel on the right, where you can freely change values such as size, color, and position.
