Quote - Can someone tell me if FaceOff's V4 Skin Realism Kit available at Daz needs updating to work with Poser Pro or not ?

It should do as the dialogs look to be using Poser's own GUI toolkit stuff.

Quote - Also - are there any other Python scripts that will need downloading again for use in Poser Pro apart from Occlusion Master and Unimesh Realism Kit?

If the script has a GUI, run it, if it works your golden, if it fails, post the details (script name, author and exception message) so someone can suggest appropriate further action.
