Hi 3D Developers,

Sketchfab viewer is a good tool for you to demonstrate 3D models. With CC 2.0 launch, the new “Upload to Sketchfab” function lets you directly publish 3D characters straight to Sketchfab to share your content. You can export the character along with its motion clips, facial morph expressions, and PBR textures. This allows users to see the details of 3D character asset and animate it in real-time. 
We encourage you to upload your creation to Sketchfab, and share the link on the product page in Marketplace.

--- New Method (effective on July 19th) --- 
Developer can insert multiple Sketchfab links on the product edit page of the Marketplace backend, and the Sketchfab 3D viewer will be directly embedded on the product page.
