Hhow can I invert a SDF ..? Dec. 3, 2018, 10:32 a.m.

A caveat: I just checked with Convert, and it looks like Convert produces polygons that have opposite winding from the original, unless Invert Sign is on or the SDF has been otherwise inverted. Using VDB from Polygons and Convert VDB gives self-consistent results, though to invert it with the Volume Wrangle snippet above, you'll need to turn on Bind Each Volume to Density.
