Is there a service that helps me creating custom Amazon Sumerian Host avatar, like Luke?

Hi there!

Thank you for reaching out. My name is Geovanni from AWS Support Team.

The Amazon Sumerian service is no longer accepting new customers and existing support for the service (including customer resources) have already been deprecated. We therefore recommend that you move any future projects to the new Babylon.js-AWS experience and publish your web app using a service like AWS Amplify Hosting.

For building avatars you can use our open source Amazon Sumerian Hosts JavaScript library on GitHub which supports BabylonJS, our recommended 3D web rendering engines.

• BabylonJS offers the BabylonJS Editor which provides visual editing capabilities very similar to what Sumerian developers were used to with the Sumerian editor.
• We provide a plug-in for the BabylonJS Editor that makes it easy to deploy your BabylonJS scenes to AWS Amplify with just a few clicks, much like the Sumerian editor's one-click publish feature.

You can view a sample of example video applications using BabylonJS in this YouTube playlist. You'll find the code for those examples in the GitHub repository linked above.

Thank you for your interest in AWS services. I hope the above information helps. Have a nice day.
