This is the actual collider

Not a stand-in. Every triangle below ships inside the .usdz — it is the geometry PhysX collides against. Pick an asset, drag to orbit, then push it and see whether it slides or goes over.

Why colliders and not a pretty render. A render tells you nothing about whether the physics is any good. Most marketplace assets hide a bounding box behind a nice texture, and your robot then collides with a shape the object does not have. Every hull you can see here was produced by convex decomposition of the real mesh — — of them on this asset — and they are what ships.

Honest labelling. The drop animation is a visual replay for scale and proportion. The numbers in the drop-test panel come from harness/03_droptest.py running pybullet at 240 Hz, included in every download so you can re-run them. The slide-and-tip figures are statics you can check by hand: F_slide = µ·m·g and F_tip = m·g·(b/2)/h, with the centre of mass assumed at the geometric centre.

Simulated results for synthetic assets. Not laboratory tests and not certifications. Mass values are declared specifications assigned during authoring, not measurements of a physical object. 3DS Bull is not a testing laboratory.
