Face Group Boundaries Node¶

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 (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 (Eigenschappen)¶

Deze node heeft geen eigenschappen.

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 UV Unwrap Node, this node is used to turn the face sets (right cube) into a UV map for a texture (left cube).
