CharacterStudio vs in3D

CharacterStudio is a free browser toolkit for creating and optimizing 3D VRM character avatars. You can build characters with preloaded traits, point-and-click controls, a color picker, your own models and textures, or a manifest.json file. Imported models must use VRM format, with version 0.0 recommended. Texture replacement works by dropping an image into the browser, ideally using UVs that match the base mesh. Creations export as GLB, VRM, or screenshots, and programmable animations are listed. A one-click optimizer can merge skinned meshes and atlas textures; the documentation says this can reduce an avatar to one draw call. Batch export can randomize outputs or follow metadata schemas. Rendering uses Three.js and WebGL. The code is open source under the MIT license. JSON assembly and export is documented for batch Anata VRMs but remains a work in progress for general use.

in3D is a mobile app that creates human avatars through 3D body scanning. During a scan, it records video and TrueDepth data through the phone camera; the site says avatars can be created within a minute. Models can be exported in FBX, GLB, or USDZ formats. The maker lists SDKs for Unreal Engine and Unity, and says its Web SDK and API can integrate avatars into apps on any platform. Avatars are described as having a Mixamo-compatible rig and a 2048×2048 texture. The developer portal says API-created avatars can be used in commercial or non-commercial games, experiences, videos, and metaverses, but not to create competing 3D scanning technology or to sell as NFTs or paid 3D model distributions. The privacy policy says only video and photos recorded in the app are uploaded, with Google Cloud Platform and Amazon Web Services used for processing. It says the files are encrypted with a key stored locally on the mobile device. Free API testing costs nothing and is limited to two scans per day; 100 scans cost $100 as a one-time purchase.
