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.

Category

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.
