OK. I'll try that search.

Actually, what I want to do is to REPLACE all the Transparency Nodes, but none of the Texture Nodes. And vice-versa.

Actually, I found a reference in the online Poser documentation that says you can call a script out of a pz2 file. The mt5 and mc6 files have a similar structure, and I tried it with them. It worked. This gives my another set of things to try.

So I've got a couple of avenues to go down. Options are always good.

Many thanks.
