Is Edge Manifold Node

The Is Edge Manifold node outputs a boolean value indicating whether each edge in a mesh is manifold. A manifold edge is shared by exactly two faces and has consistent face normals, meaning it is part of a continuous surface without gaps or branching edges.

This node is useful for detecting mesh topology issues or isolating boundary or non-manifold edges.

Inputs

This node has no inputs.

Outputs

Manifold

Boolean value that indicates whether each edge is manifold. True if the edge is shared by exactly two faces; false otherwise (for example, if the edge belongs to one face, more than two faces, or no faces at all).
