Lock Normals

Icon

Creates custom normals for a mesh if none exist. Can also be used to convert between "Free" and "Tangent Space" normals, see the Blender Docs:

Options

  • Custom Normal Type: How to store custom normals:

    • Free: Store custom normals as simple vectors in the local space of the mesh. This is efficient and fast to evaluate but does not support deformation.
    • Tangent Space: Store normals in a deformation dependent custom transformation space. This method is slower, but can be better when subsequent operations change the mesh without handling normals specifically.

  • Normal Domain: When Custom Normal Type is set to Free:

    • Face Corner. Store normals on face corners, allows for sharp edges.
    • Point. Store normals on points, cannot have sharp edges.
