#### How may the scene 3D model be used?
Please download and compress the folder containing the scene 3D model, locate the "mesh.obj" file, and then open it in 3D software for editing.

#### How can I upload the 3D model of the edited scene?
1. The 3D model must consist solely of triangle-shaped faces;
2. After altering the model in a 3D application, it is recommended to bake the model's texture, which should be managed under 5MB;
3. Save and compress the OBJ file, then upload (only ZIP format is supported) all files (including OBJ, MTL, and JPG (texture)).

#### Notice:
1. Please verify that the file names of the OBJ and compressed package are identical to those previously downloaded;
2. Please manage the file size well when uploading in order to maintain the browsing effect.
