What are we driving on?

Each part is a mesh/material primitive from the visible model. Families are inferred from names; they need human review. Up to 16 area-distributed points per part are checked against the actual ground sampler. A difference over 8 cm is flagged on expected ground parts. Selected barrier faces are checked for inclusion in the current collision bake.

Overlapping layers, steep terrain and decorative objects can explain differences. “Sampled match” is not a full-track certification. Grip and resistance are configured values, not measured driving results. This survey does not yet test tyre response, seams between probes, or collision response while driving.

Geometry previews show untextured, sampled source triangles. Orange points mark visual probe positions; green or red points show physical support at those positions.
