Avatar SDK Avatar API vs MakeHuman

Avatar SDK Avatar API turns a photo into a rigged 3D avatar through a REST API. It offers realistic or cartoon styles and head or full-body pipelines, returning GLB, glTF or FBX models with facial blendshapes. Full-body avatars also include a skeleton and are compatible with Mixamo animations and real-time lip-sync through LiveSpeak. The output is described as compatible with Unity, Unreal Engine, Blender, three.js and Babylon.js. Full-body generation takes about 40 seconds and runs asynchronously: an application submits a photo and polls for the completed model. The API can run as a hosted cloud service or on-premise using Local Compute inside customer infrastructure. Enterprise Cloud REST API access is priced according to customer volume; a 7-day trial is listed, with no free plan. Access uses OAuth 2.0 tokens. Documented limits are 75 requests per minute per unique PlayerUID in Client access mode and 150 per minute per account in Developer access mode. The maker recommends clear, front-facing photos with even lighting and a neutral expression or slight smile.

MakeHuman creates customizable 3D human characters by blending adjustable features on a base mesh. Character targets let users alter traits from sex and muscle tone to earlobe shape. A built-in downloader provides access to community assets, and the application includes a render engine and parametric modeling. Meshes can be exported in Collada (DAE), FBX, Wavefront OBJ, STL, and Ogre3D formats; projects can also be saved in MHM format. Exporting meshes is one-way: MakeHuman cannot open those exported formats again. BVH is the listed rig format, and the documentation says MakeHuman 1.1.0 does not officially support animation inside the application. For Blender workflows, MPFB can communicate directly with MakeHuman instead of depending on file exports. It runs as desktop software on Linux, macOS, and Windows. The plan is free. The site says core assets including the base mesh, targets, and skins are CC0, with no paywall or email requirement for downloading.
