Normals

The Normal Edit Modifier can be used to edit normals.

The Weighted Normal Modifier can be used to affect normals by various methods, including Face Strength (see below).

You can also copy normals from another mesh using Mesh Data Transfer (operator or modifier).

Flip

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Flip

This will reverse the normals direction of all selected faces. Note that this allows you to precisely control the direction (not the orientation, which is always perpendicular to the face) of your normals, as only the selected faces are flipped.

Recalculate

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Recalculate Outside and Mesh ‣ Normals ‣ Recalculate Inside

Tastenkürzel:

Shift-N and Shift-Ctrl-N

These tools will recalculate the normals of selected faces so that they point outside (respectively inside) the volume that the face belongs to. The volume does not need to be closed; inside and outside are determined by the angles with adjacent faces. This means that the face of interest must be adjacent to at least one non-coplanar other face. For example, with a Grid primitive, recalculating normals does not have a meaningful result.

Set from Faces

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Set from Faces

Set the custom normals at corners to be the same as the face normal that the corner is part of.

Rotate

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Rotate

Tastenkürzel:

R N

This is an interactive tool. As you move the mouse around, the selected normals are rotated. You can also invoke the Rotate Normals tool by pressing the Rotate transform key R, followed by N.

Point to Target

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Point to Target

Tastenkürzel:

Alt-L

All selected normals are set to point from their vertex to the target after confirmed by Return or LMB.

A target is set by the keys:

• The mouse cursor M

• The pivot L

• The object origin O

• The cursor (set at this click) Ctrl-LMB

• A mesh item selection (set by this click) Ctrl-RMB

Modus

The tool operation can be modified; if one of the following keys has been previously pressed:

Align A

All normals will point in the same direction: from the center of selected points to the target.

Spherize S

Each normal will be an interpolation between its original value and the direction to the target.

Invert I

The normal directions are reversed from what was specified above.

Reset R

Will reset the custom normals back to what they were when the operation started.

Merge

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Merge

Merge all of the normals at selected vertices, making one average normal for all of the faces.

Split

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Split

Split the normals at all selected vertices so that there are separate normals for each face, pointing in the same direction as those faces.

Average

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Average

Average all of the normals in each fan of faces between sharp edges at a vertex.

Copy Vectors

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Copy Vectors

If a single normal is selected, copy it to an internal vector buffer.

Paste Vectors

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Paste Vectors

Replace the selected normals with the one in the internal vector buffer.

Smooth Vectors

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Smooth Vectors

Adjust the normals to bring them closer to their adjacent vertex normals.

Reset Vectors

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Reset Vectors

Put normals back the to default calculation of the normals.

Select by Face Strength

Referenz

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Select by Face Strength

Another way to affect normals is to set a Face Strength on the faces of the model. The Face Strength can be either Weak, Medium, or Strong. The idea is that the Weighted Normal Modifier can be set to pay attention to the Face Strength as follows: When combining the normals that meet at a vertex, only the faces with the strongest Face Strength will contribute to the final value.

For example, if three faces meet at a vertex and have the face weights weak, medium, and strong, then only the normal associated with the strong face will be used to set the final result.

Use the submenu to pick one of Weak, Medium, or Strong. Then this tool selects those faces that have the chosen face strength.

Set Face Strength

Modus:

Edit Mode

Menü:

Mesh ‣ Normals ‣ Set Face Strength

Use the submenu to pick one of Weak, Medium, or Strong. Then this tool changes the Face Strength of currently selected faces to the chosen face strength.
