Houdini 20.5 Nodes Geometry nodes

Point Split geometry node

Splits points shared by multiple vertices, optionally only if the vertices differ in attribute values.

Since 18.0

For each point in the input group that is shared by multiple vertices, Split Points creates separate points for each vertex, so that the points will be unshared (“unique”).

Optionally, one or more vertex or primitive attributes can be specified to limit the splitting such that new points will only be created for clusters of attribute values that differ by more than a given tolerance. The vertex or primitive attributes can then be optionally promoted to a point attribute.

This operation is useful for promoting vertex or primitive attributes to point attributes without either creating a lot of points or destroying the seams in those attributes.

Parameters

Group

The point, vertex, or primitive group to split. For vertex groups, new points will only be created for vertices in the group. For primitive groups, new points will only be created for vertices in primitives in the group.

Attributes

The names of the vertex or primitive attributes to perform the test on, optionally using wildcards to match many attributes. New points will only be created for clusters of attribute values that differ by more than the given Tolerance. This is useful for splitting points around uv islands (uv), cusped normals (N), or primitive pieces (name). Named groups can also be specified here, to split just around the boundary of a primitive or vertex group.

Tolerance

The maximum error in any dimension of the attribute before it will be split.

Promote to Point Attribute

Whether to promote the attributes to point attributes.
