Cant rename Boolean node to DiffuseTexture

In Fusion 8, I can rename a Boolean Node to just about anything

DTexture
skhdfvkdjhkjdh
etc

But for some reason I can't rename it to DiffuseTexture. Is that now a reserved internal name or why can't I rename it to that?

Yep.
You're most likely running into a name-clash there.
Try "myDiffuseTexture"...

Thought as much, thanks Eric.

Strange though, seemed to work fine in 7. I geuss a few things have changed since then
