These are nodes for working with Mesh data.

Set Mesh Normal

The Set Mesh Normal node is used to modify custom normals on a mesh, providing control over shading smoothness and surface appearance. This is useful for adjustingnormalsmoothness, sharp edges, and tangent-based effects

Input

Mesh

Input mesh.

Properties

Mode

Sharpness

Controls the intensity of edge sharpness. Higher values create stronger shading contrasts between faces.

Store the sharpness of each face or edge. Similar to the "Shade Smooth" and "Shade Flat" operators.

Entry	What it does
Remove Custom	Removes custom normals previously set by the user on the original mesh data when enabled.
Edge Sharpness	Sets the normal sharpness to the edge domain to “flat”.
Face Sharpness	Sets the normal sharpness to the face domain to “flat”.

Free

Allows direct manipulation of normals as free vectors, rather than constrained by geometry. Useful for custom shading effects and non-destructive normal adjustments.

Domain

Attribute domain to store the free custom normals.

Point
Face
Face Corner

Note: Default object normals are stored to Facecorner, this will “pass-through” the normal data. Face normals will make “flat” sharp edges.

Tangent Space

Adjusts normals relative to the surface tangentto store the source meshes normals.Storesnormals in a deformation dependent custom transformation space.

Note: This method is slower, but can be better when subsequent operations change the mesh without handling normals specifically.

Custom Normal

Vector Field based on the normal.

Outputs

Geometry
