Hi, if you are using transparent 360 product images (pngs), you can force the viewer to use a transparent background by overriding the viewer background style in your theme CSS, or try to use the background property of the shortcode like this:
Code:
[wr360embed name="view2" width="100%" background="rgba(0,0,0,0)" config="url-of-the-viewer-config.xml"]
We haven't tested this background value, i.e rgba in the wordpress shortcodes but it will likely work. If it doesn't work, let us know and we will advise on how to override the viewer background in your theme CSS.
The end result is that the viewer will be transparent so if your parent container on this page has a background image, it will be visible.
