You can edit the geometry of a 3D object in VStitcher and Lotta.
To edit the geometry:
If the Materials tab is not already open, on the Resources tabs, click Materials.
Click the 3D object. Details of the object are displayed in the Context view.
In the Context view, click the image that is displayed in the 3D Trim section.
The 3D Object Editor is displayed.
Click to expand the editor.
Edit the properties as required.
Click to open the Customize 3D Object dialog box. For more information, refer to Customize 3D Object dialog box in How to Import a 3D Trim Object.
Click to reset the size to the original object size.
Adjust the X, Y, or Z properties as required.
Note: By default, these values are dynamically linked so that a change in one automatically causes a proportionate change in the other values.
Click to unlink the size properties.
Close the 3D Object Editor.
