Question: I'm looking for a solution that allows me to create realistic digital humans for e-commerce and metaverse applications.

Ready Player Me is a self-contained avatar maker that offers a higher-end, customizable option with thousands of variables. It makes it easier to integrate with popular game engines like Unity and Unreal and offers a full set of tools, including a Developer Studio for setup and a large library of branded assets. It's geared for social experiences, virtual meeting tools and games, so it's a good option if you want to expand your online presence with digital accessories.

Meshcapade uses more advanced generative models like SMPL to create photorealistic digital avatars from relatively limited input data. The service accepts motion input from text, video and images and works with several game engines and graphics software. Meshcapade is designed as an avatar-as-a-service for e-commerce and the metaverse, with a portable design and detailed API documentation and a free trial option for easy testing.

For a more AI-based approach, Avaturn turns 2D selfies into photorealistic 3D avatars with more than 10,000 customization options. Avatars can be exported to Unity, Unreal Engine and other software, and are ready to be animated. Avaturn has an SDK for developers and several pricing tiers, so it's good for everything from casual use to enterprise deals.
