Shows the sealed voids of a Solid — closed hollows powder or resin cannot drain from — as a field: 1 inside a sealed void, 0 elsewhere.
The Solid to search for sealed voids.
Grid cells along the Solid's longest side, 8–128. Finer grids resolve narrower drain channels.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The field read as a Solid whose surface is where the field is zero.
The box the field is evaluated in.
The field with its sign flipped (−f), which swaps inside and outside.
The field divided by its gradient length (f/|∇f|) so it reads close to a true distance; the zero set does not move.
