Name: "API Tests" Type: Project Version: "1.51" EngineVersion: Min: "2026.2" Behaviour: Hide Category: Examples Description: > Strict determinism test project for the External Action Gate gRPC API. Each scene pairs a robot with a control mode and a Python test under Assets/api-scripts/ that drives it purely over the gated Step() loop and checks bit-exact repeatability: the Panda and Piper arms; the Unitree Go2 (in-engine and external locomotion) with LiDAR-scan, RGBD-camera and reset_scene checks; and the Unitree G1 three- and five-finger humanoids in base, engine, external, IK-engine and IK-external variants. The four arm-IK scenes additionally assert that the arm actually tracks its commanded target, not just that the run replays identically. A pick-and-place scene shows engine-side C# driving a G1 through a waypoint sequence with draggable target empties and debug gizmos. A lidar-material scene puts glass, water, mirror and retroreflector panels in front of a diffuse backstop, exercising the NIR material model: the voxel bake that maps a collision hit back to its Hazel material, per-return intensity and range-calibrated reflectivity, and pass-through secondary returns off the wall behind. run_all_tests.py sweeps every scene and reports pass/fail, installing requirements.txt into its test interpreter first.
