If your GLB file has errors or isn't behaving like a single object, you can use specialized fix tools to automate the repair process:

To make a model a "solid piece" in a (GL Transmission Format) file, you typically need to use a 3D modeling tool like Blender to join separate meshes into one and ensure the geometry is "manifold" (water-tight). 🛠️ Key Steps in Blender Join the Meshes : Select all the separate objects you want to combine. Press Ctrl + J to join them into a single mesh object. Make it a Single "Solid" (Manifold) :
