Houdini 20.0 Nodes Geometry nodes

Labs Delete Small Parts geometry node

Removes pieces based on connectivity and size

This node calculates the size of each piece on a mesh and deletes the ones that fall below a certain size threshold.

This is incredibly useful in Photogrammetry and Fluid Mesh cleanup, where you might have a lot of droplets or small disconnected pieces that you don’t care about.




How the size is determined

Extract Largest Piece

Ignore the threshold and only keep the single largest piece


Pieces with the Area or Perimeter smallest than this will be removed

Invert Result

Invert the operation


Calculate Piece Attribute

Toggle if the tool should be determining connectivity

Piece Attribute

If the tool shouldn’t be calculating connectivy, what is the attribute that determines what a piece is
