Create Normals if missing

What is it about?

This page documents the Create Normals if Missing node of the Scene Nodes system in Cinema 4D. It generates point normals only where none exist, preserving existing data — the non-destructive variant of Generate Point Normals.

The function of this Node is identical to that of the Generate Point Normals Node, except that new normals are calculated only if normals do not already exist. Existing information about normals is not overwritten with this Node.

Here, a simple geometry is created and then normalized.

On the left the generated geometry without assigned normals, on the right with normals.
