After you push a 3D model from Freakout to a Shopify product, it appears among that product's media in Shopify Admin. To show it in the product gallery on your storefront, the product must be published to the Online Store sales channel and your theme must support 3D media.
Shopify's Online Store 2.0 themes, including Dawn and other free themes built by Shopify, support 3D models without adding custom code. Use an up-to-date version of the theme.
If you use an older theme, update it or switch to a theme that supports 3D media. For a third-party or custom theme, check its documentation or ask its developer whether the product gallery supports 3D models.
If the model is visible in Shopify Admin but missing from the storefront, check the product template in the theme editor. If the product uses an alternate template, inspect that assigned template and make sure its product gallery displays 3D media.
For Shopify's media requirements and theme guidance, see Shopify Help: Product media and supported themes for 3D models.
