# Recompute Normals

Recompute Normals allows users to recompute the Normals for a selection of skeletal meshes.

The Normals are computed in such way that there is no seam if multiple skeletal meshes are selected as the meshes are getting welded in the underlying algorithm and the normals are then projected back to the Skeletal Meshes.

| Skeletal Meshes         | Array of skeletal Meshes                                                                                                                                                  |
| Update DNA Asset        | Bakes Normals to DNA Asset Mesh Data if available. This is intended for Meta Humans only.                                                                                 |
| Merge Vertex Tolerance  | Edges are coincident if both pairs of endpoint vertices are closer than this distance                                                                                     |
| Merge Search Tolerance  | Edges are considered as potentially the same if their midpoints are within this distance. Due to floating-point roundoff this should be larger than MergeVertexTolerance. |
| Merge Only Unique Pairs | Only merge unambiguous pairs that have unique duplicate-edge matches                                                                                                      |

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.meshmorpher.com/editor/advanced-operations/recompute-normals.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
