Geometry Nodes

Every Zen Sets group can be used in Geometry Nodes. Attribute implementation depends on Sets or Parts mode

Parts Mode

There is a fixed attribute for every Parts mode. Every group has its own unique integer identifier within the current Scene.

Mode	Mesh Element	Attribute Name
Vert Parts	Vertex	zen_vert_u_hash_layer
Edge Parts	Edge	zen_edge_u_hash_layer
Face Parts	Face	zen_face_u_hash_layer
Face Maps	Face	face_maps

Sets Mode

Every group in Sets Mode is exposed as separate integer attribute with 1 value if elemement belongs to the group and 0 if not.

Attribute Names Match Group Name

If option ‘Sync Attribute Name’ is set attribute will have the same name as the group name

Attribute Names Are Unique

If option ‘Sync Attribute Name’ is unset then attribute will have unique name with the next format:

zen_{vert|edge|face}_{128-bit uuid}
