HPMAXCONTOURPOINTS sets the maximum number of points on the contour (outline) that a hatch entity can contain and still be rendered. Hatches do not render if the number of points exceeds the specified value. This can reduce the render time while zooming in on hatches with a large number of contour points. The default value of this variable is 100,000. Setting HPMAXCOUNTERPOINTS to 0 disables the check.
