Syntax
TFunction< FVector3d(const FVector3d &)> PointConstraintFunc
Remarks
Optional function that will be used to project potential snap points onto constraints. Note that Line/Curve constraints are still respected, so eg if this projects to a 3D grid, then when calculating possible line-snap positions, the 3D grid point will be projected back onto the line targets.
