Hi Martin,
Thanks. It looks like somehow along the way the driver was only baked for Pencil B and not Pencil A, so I think that explains why it wasn’t appearing in the graph editor.
I progressed further along in the lesson and noticed when I applied the material to Pencil B, the wood texture looks totally different, but I’m not sure why? As far as I can see they use the same identical material.
