Houdini 20.0 Nodes Geometry nodes

PolyLoft geometry node

Creates new polygons using existing points.

This node generates meshes of triangles by connecting (i.e. lofting/stitching) the points of open or closed faces without adding any new points. Polyloft can also connect groups of unrelated points in a similar fashion. The faces and the point groups need not have the same number of points.

The optional input specifies the rest geometry, typically the copy of the main input at a specific face (usually 1). This forces the point order to remain constant throughout the animation and prevents the triangular stitch from popping as the geometry deforms. If you specify face or point groups for lofting using rest geometry, make sure they are defined in the second input.


Connect Closest Ends

Start stitching at the two closest points, and handle arbitrary face orientation and start vertices

Consolidate Points

Fuse neighboring points before stitching


Threshold distance for consolidation


Distance minimization goal:

2-Point Distance

Default stitching target

3-Point Distance

May help avoid intersections

U Wrap

Close the stitch in U (close each cross-section)

V Wrap

Connect first and last cross-sections

Create Polygon Group

Place the generated triangles into a group

Collinearity Tolerance

The tolerance for the collinearity check. This check prevents the building of a triangle using three collinear points.



Stitch a set of faces by connecting their control vertices


Subset of faces to loft

Keep Primitives

Preserve the cross-sections after stitching



Stitch up to 6 sets of points, each set acting as a cross-section

Group 0-5

Point group
