FVector3i PointToIndex
(
uint32 Level,
const FVector3d & Position
) const
Remarks
Warning: result here appears to be unstable (due to optimization?) if any of the position values are on the border of a cell (in testing, pragma-optimization-disabled code produced off-by-one result from calling this function)
