Normal Transfer

Normal Transfer Icon

Transfer Normals from other mesh objects. This can be useful in a variety of situations:

  • blend
    Blend between meshes without affecting geometry.

  • fix
    Fix / smooth shading of bad topology. See also Smooth Normals and Boolean Pro

  • foliage
    Create better shading for foliage cards.

  • floater Match normals of "floater" decals. See also Surface Project

Examples

Examples can be found in the Normal Modifiers scene in the example file

examples

Options

  • Normal Domain. Whether normals are stored on points (smooth) or face corners (allows sharp edges).

Transfer Geometry

Choose which meshes to transfer normals from.

  • Object Count. How many mesh objects to transfer normals from.
  • Objects. Choose individual mesh objects to transfer normals from.
  • Collection. Choose a collection containing mesh objects to transfer normals from.

Transfer

  • Method. How to sample the normal from target surface:

    • Closest Surface. Sample normal at closest target surface.
    • Project Object Direction. Raycast-sample target geometry in object space.
    • Project Island Normal. Raycast-sample target geometry along the average mesh island normal.
    • Project Source Normals. Raycast-sample target geometry along mesh normals of this object.

  • Ray Length (Project Methods). Maximum length of raycast to target surface.

  • Direction (Project Object Direction Only). Direction in object space to raycast (default is -Z).

  • Automatic Masking. Mask falloff for transferring normals, see Mask Falloff
