BlendNormal
example file
This example shows how to blend normal direction using a Sequence Blend SOP.
The Sequence Blend SOP can blend a combination of shapes, colors, textures, and normals between two or more geometries in a sequential manner.
A single geometry is created and normals are added to the points using two separate Point SOPs. A Sequence Blend SOP blends between the two inputs' point normals.
Turn on Display Point Normals in the viewport’s Display Options to see the normals
