OK, I'd started to think this, too.

Right, I made the declaration and return modifications (made it return
the length of the calculated displacement vector) and it worked fine.
On further testing I've found that the shader pigment will exit with the

renderer hits the shaded object. This may help to track the problem?

I'll post an example image using the shader as a pigment ...
Bye for now,
