PointsWithinToleranceTest

This is the function we use to determine if a point on a corner/edge is close enough to the hit-test ray to treat as a "hit".

Windows

MacOS

Linux

Syntax

TFunction< bool &, const FVector3d &, double ToleranceScale)> PointsWithinToleranceTest

Remarks

This is the function we use to determine if a point on a corner/edge is close enough to the hit-test ray to treat as a "hit". By default this is Euclidean distance with a tolerance of 1.0. You probably need to replace this with your own function.
