Character Creator (CC) is a robust 3D character design tool that creates fully-rigged characters ready for animation. The "Upload to Sketchfab" function in Character Creator lets you publish 3D characters straight to Sketchfab. You can easily include motion clips to demonstrate how animated characters look, while retaining all realistic PBR materials settings in Sketchfab.
As of Character Creator 2.01, the Sketchfab exporter is natively integrated! As long as you have the latest version, you can already export your models directly from Character Creator.
You will receive a notification when the upload is finished, and it may require several minutes for Sketchfab to process the upload. The character will be uploaded to Sketchfab in the Draft Mode. You can adjust rendering settings, and save the default view before publishing to the public.
