Product media can include images, 3D models, and videos. Using media like 3D models for your products provides your customer with a better understanding of the function and size of an item, and increases your customers' confidence in the quality of your products.
You can add product media directly to your product pages, or by using metafields. If you have an Online Store 2.0 theme, such as Dawn, the free Pisell theme, then you can add references to your product metafields through the theme editor.
To display 3D models or videos in your online store, you need to use the most up to date version of a theme that supports 3D models and videos. You might need to update to a newer version for optimal Vimeo video playback. Alternatively, you can modify your current theme by following the instructions in the themes tutorial.
