Remarks

Compute base/detail mesh correspondence by raycast Find point on Detail mesh that corresponds to point on Base mesh. Strategy is: 1) cast a ray inwards along -Normal from BasePoint + Thickness*Normal 2) cast a ray outwards along Normal from BasePoint 3) cast a ray inwards along -Normal from BasePoint We take (1) preferentially, and then (2), and then (3)

If all of those fail, if bFailToNearestPoint is true we fall back to nearest-point,

If all the above fail, return nullptr a pointer to the hit mesh, otherwise nullptr.
