Synth framework brings on-device RL humanoids to Unity

A Reddit launch post open-sources three Apache-2.0 Unity packages: synth-core for MuJoCo-based humanoid rigging, synth-training for in-editor and on-device SAC with TorchSharp, and synth-vr for Meta Quest mixed-reality interaction. Together they form an end-to-end workflow from importing a humanoid to training and physically interacting with it in-room.

// ANALYSIS

This is a credible infra-first launch that closes a real gap between physics simulation, reinforcement learning, and embodied XR interaction inside one Unity-native stack.

–On-device SAC in Unity (including Quest CPU paths) removes the usual Python server dependency and lowers prototyping friction.
–MuJoCo-backed rig generation from common avatar formats (Daz/Mixamo) makes experimentation much faster for embodied AI developers.
–The VR package adds practical MR interaction primitives (hand physics, room setup, passthrough) instead of just simulation demos.
–Open Apache-2.0 licensing across all three repos increases reuse potential for research and indie tooling.
