Drag & drop a file onto this window, or use the toolbar below.
HDRI always lights the scene. Set BG → Solid to hide the sky.
Type a size in mm to rescale the model, then download it as GLB. Pick the unit 1 scene unit represents in your file (GLB/GLTF is metres by convention).
Names are written into the downloaded GLB (node + mesh names), so other tools and configurators read them back.
