If the object is featured against a colored backdrop (non-white) it may cause problems when zooming-in or when resizing an embedded 3D View.
To avoid this, you should change the iFrame background color. There are two ways of doing this.
In the Easy 3D Scan software, go to the Background section of the Edit tab, click “Select color” and click on the backdrop.
Go to your Cappasity account, click “Edit SKU” right below the 3D View and select the background color.
For a better understanding, watch the video tutorial:
