Why it happens
The camera path ignores the bounding volume and the near plane cuts into the mesh.
Check / fix block
FreeCheck: clamp the minimum camera distance with the bounding-sphere radius; capture the scroll-driven path at 0, 25, 50, 75 and 100% and none of the five frames cut the model.
The library itself is public. On a card, the first check is free; the rest and the contact sheet are Pro.
