Quote - I made a slight mistake, I should have said change the word "mtlCollection" to "figure".

Once you have saved the edited file, that's it, job done. It is a now a MAT pose file and will work on your figure. The only thing left to do is make a thumbnail image for it.

Ahhhh, Thank you.
This helps so much.
I promiss to name my first born after you.
Smiles and Happy Renders to you both for your help
