These tools are to help cleanup degenerate geometry and fill in missing areas of a mesh.
The Decimate Geometry tool allows you to reduce the vertex/face count of a mesh with minimal shape changes.
- Ratio of triangles to reduce to.
- Vertex Group
Use the active vertex group as an influence.
- Strength of the vertex group.
- Inverts the vertex group.
- Maintain symmetry on either the X, Y, or Z axis.
This tool works similar to the Decimate Modifier.
This tool can take a large selection and detect the holes in the mesh, filling them in.
This is different from the face creation operator in three important respects:
- Holes are detected, so there is no need to manually find and select the edges around the holes.
- Holes can have a limit for the number of sides (so only quads or tris are filled in for example).
- Mesh data is copied from surrounding geometry (UVs, vertex colors, multi-res, all layers), since manually creating this data is very time-consuming.
Make Planar Faces¶
The Make Planar Faces iteratively flattens faces. This can happen with faces over three vertices and it is a common convention that faces should be kept planar.
- Distance to move the vertices each iteration.
- Number of times to repeat the operation.
Split Non-Planar Faces¶
This tool avoids ambiguous areas of geometry by splitting non-flat faces when they are bent beyond a given limit.
Split Concave Faces¶
This tool can be used to convert any concave face to convex by splitting the concave into two or more convex faces.
Delete Loose Geometry¶
This tool removes disconnected vertices and edges (optionally faces).
This tool collapses / removes geometry which you typically will not want.
- Edges with no length.
- Faces with no areas (faces on a point or thin faces).
- Face corners with no area.
