The purpose of this  script was to ease the upgrade of a character's material. My setups are fairly simple: on the Cycles part, there's a root Cycles node, to which is attached a compound node

How to detect and replace the said compound node: no problems
How to copy-paste a selected node: I think I know how, using the MaterialManager
How to select a specific node: no idea, but I know how to upload a specific MT5, delete any root nodes as these specific nodes don't have such node. Then using the MaterialManager: selectall, then copy, then paste elsewhere

the problem using this steps:
- can't create a new material, and then delete it afterwards
- can create a new layer, but how to load the MT5 in that layer instead of the base layer?

One solution could be to create specific MT5 that are ready-to-load in a specific layer.

I'll check this after my job.
