Testing 3D materials, motion and simulation
Start with a delivered assembly, or choose a pair of articles on materials, motion or simulation. Each pair explains a check and the limits of its evidence.

The shared scene
Accepting Agent-Generated 3D Part 2 of 5The 70 mm Gap Our Review Would Have Missed
Inspect the delivered assembly and the 70 mm gap its producer caught between saved frames. This is the shared example behind the focused checks.
-
Materials and textures
Accepting Agent-Generated 3D Part 3 of 5Checking Material Delivery in Agent-Generated 3D
Check bindings, dependencies and decoding, and reproduce a reader bug that falsely accepted missing textures.
-
A Texture Pass Covers Only the Pixels It Compared
After the files load, define which pixels must match and what rendered appearance still needs review.
-
Motion and connections
Accepting Agent-Generated 3D Part 4 of 5Checking Motion in Agent-Generated 3D
Check duration and positions in elapsed seconds, including a clock-rate change that an earlier contract accepted.
-
Checking Whether a Moving Connection Stays Together
Extend position checks to attachment between moving parts, and see why the sampling schedule belongs in the result.
-
Physics and simulation evidence
Accepting Agent-Generated 3D Part 5 of 5Evaluating Physics Configuration and Simulated Behavior
Separate valid physics configuration from behavior that meets the task, including solver sensitivity and assumed friction.

When a Simulation Result Can Count as Evidence
Tie a runtime trace to the saved scene, then use the brief to decide whether a measured slide calls for repair.
