Dissolve Mesh Elements

Functionality

Dissolve will remove the geometry and fill in the surrounding geometry. Instead of removing the geometry, which may leave holes that you have to fill in again.

Modifiers -> Modifier change -> Dissolve Mesh Elements

Inputs

• Verts - vertices of given mesh(es)

• Edges - edges of given mesh(es)

• Faces - faces of given mesh(es)

• Mask - mask of vertices, edges or faces which should be dissolved

Parameters

• Mode

  • Verts. Remove the vertex, merging all surrounding faces. In the case of two edges, merging them into a single edge

  • Edges. Removes edges sharing two faces (joining those faces)

  • Faces. Merges regions of faces that share edges into a single face

• Use face split. When dissolving vertices into surrounding faces, you can often end up with very large, uneven n-gons. The face split option limits dissolve to only use the corners of the faces connected to the vertex.

• Use boundary tear. Split off face corners instead of merging faces.

• Use verts. Undocumented

1. Original mesh.

2. Face Split: Off, Tear Boundaries: Off.

3. Face Split: On, Tear Boundaries: Off.

4. Face Split: On/Off, Tear Boundaries: On.

Outputs

• Verts - vertices of dissolved mesh

• Edges - edges of dissolved mesh

• Faces - faces of dissolved mesh

• Verts ind - vertices indexes of mesh before dissolving operation

• Edges ind - edges indexes of mesh before dissolving operation

• Faces ind - faces indexes of mesh before dissolving operation

• Loops ind - loops indexes of mesh before dissolving operation

Note: `Index` sockets can map data of mesh elements from mesh before operation to mesh after operation. For mapping operation `list item` node can be used.
