Question: Is there a platform that allows me to easily integrate avatar creation into my Unity or Unreal game engine project?

If you want to build avatar creation into your Unity or Unreal game engine project, Ready Player Me is a top contender. The service provides a customizable, end-to-end avatar system with thousands of parameters that can be used to generate avatars from selfies. It's designed to work easily with widely used game engines through open-source SDKs, and it's got a Developer Studio for fine-tuning and customization. The service also has monetization tools, making it a good fit for social experiences, virtual meeting tools and games.

Another top contender is Avaturn, which uses generative AI to turn 2D selfies into photorealistic 3D avatars. With more than 10,000 parameters for customization, including body type, hair, clothing and accessories, Avaturn avatars can be exported to 3D worlds like Blender, Unity and Unreal Engine. The service also offers an SDK for developers, who can keep game characters' real-world identities private.

For a more scientific approach, Meshcapade uses AI and machine learning to generate photorealistic digital humans. Its core technology, SMPL, is trained on vast 3D scans to learn the statistics of 3D body shapes. That means you can generate avatars with relatively limited input data and generate motion from text and video prompts. Meshcapade is designed to work with every game engine and graphics package, so it's a good choice for e-commerce and the metaverse.
