|
|
|
|
The *Face Group Boundaries Node* finds the edges which lie on the boundaries of
|
|
specified regions. These edges could be used to mark seams for UV unwrapping,
|
|
for example.
|
|
|
|
|
|
Inputs
|
|
======
|
|
|
|
Face Group ID
|
|
Identifier for which group of faces this face belongs to. All contiguous faces
|
|
with the same value are in the same region.
|
|
|
|
|
|
Properties
|
|
==========
|
|
|
|
This node has no properties.
|
|
|
|
|
|
Output
|
|
======
|
|
|
|
Boundary Edges
|
|
Selection of the boundary edges of the different face sets. An edge is
|
|
considered to be at the boundary if it lies on at least two faces with
|
|
different identifiers.
|
|
|
|
|

Combined with the :doc:`UV Unwrap Node </modeling/geometry_nodes/mesh/uv/uv_unwrap>`,
|
|
this node is used to turn the face sets (right cube) into a UV map for a texture (left cube).
