Summary: Error rendering or exporting a DSP
This was done as a test to try and get it to work - stl export and render produce errors of them

Note you shouldn't *have* to do add the low-pass offset. It obviously
should just work to have holes and does work for some hole configurations.
Our tessellation library is even intentionally built around supporting
n-manifold geometry with arbitrary holes.
The DSP implementation, however, was originally written without holes in
mind so it's taken (and will continue to take) some time to find all the
generalizations that are needed for arbitrary inputs. We need a regression
test that covers all configurations of a 5x5 (or larger) and then make sure
they're all handled correctly (raytrace and conversion).

The problem is almost certainly related to the holes. If you make sure the
input values are all any non-zero value, it should work just fine. If you
need the holes, you can subtract an intensity level with an arb8/rpp
afterwards though that might still lead to export problems (but should
