Hello! Have you tried to use the Sandbox (sandbox.babylonjs.com) to convert from GLB to babylon? Is the result the same? :slight_smile:

I tried loading the final1_old.glb into the sandbox and export to .babylon and then reload in sandbox. That seems to be working.

@xiaopangoo You seem to be mucking with the ids/names in the scene before exporting. Does it work if you don’t muck with the names?

					//material.id处理
					for(var i=0; i<scene.meshes.length;i++){
						var newId = createUuid();
						console.log(i + '--' + scene.meshes[i].name);
						console.log(scene.meshes[i].material);
						if(scene.meshes[i].material){
							console.log(i + '--' + scene.meshes[i].material.id+ '--' + newId);
							scene.meshes[i].material.id = newId;
							scene.meshes[i].material.name = newId;
						}
					}
					
					//geometry.uniqueId,geometry.id处理
					for(var i=0; i<scene.meshes.length;i++){
						var newId = createUuid();
						console.log(i + '--' + scene.meshes[i].name);
						console.log(scene.meshes[i].geometry);
						if(scene.meshes[i].geometry){
							console.log(i + '--' + scene.meshes[i].geometry.id+ '--' + scene.meshes[i].geometry.uniqueId + '--' + newId);
							scene.meshes[i].geometry.id = newId;
							scene.meshes[i].geometry.uniqueId = newId;
						}
					}
					
					//skeletonId处理
					for(var i=0; i<scene.skeletons.length;i++){
						var newId = createUuid();
						console.log(i + '--' + scene.skeletons[i].id + '--' + newId);
						scene.skeletons[i].id = newId;
						scene.skeletons[i].name = newId;
					}
					
					//id,uniqueId处理
					for(var i=0;i<scene.getNodes().length;i++){
						var tmpNode = scene.getNodes()[i];
						console.log(i+'--' + tmpNode.name + '--' + tmpNode.id + '--'+ tmpNode.uniqueId );
						//根节点名字处理
						if(i === 0){
							tmpNode.name = fileName.split('.')[0];
						}
						tmpNode.id = createUuid();
						tmpNode.uniqueId = tmpNode.id;
						console.log(i+'--' + tmpNode.name + '--' + tmpNode.id + '--'+ tmpNode.uniqueId );
						console.log(tmpNode.parent);
					}
