Quote - V4 has been around much longer than Roxie and, still, is promoted and used heavily.  Her added advantage, as a DAZ figure, is her conversion to weightmapping.  

Roxie is a Poser legacy figure and unfortunately, many legacy figures through the years have not been promoted too well.  For content, you will need to search around.  If you have PP2014, the fitting room would be your best bet to try and convert clothing.

Thanks, the penny's dropped on that question now, and I've now gone ahead and purchased V4.2 and 4.2 Morphs ++.

However, having done so and loaded her into Poser, I'm again a bit baffled because it seems to add a morph I have to load it from the content library, and only then will a morph dial appear in parameters so I can adjust it as I like. Then for each subsequent morph I have to go through the same process again and again, which seems tedious to say the least. Is that how it works with V4 in Poser, or am I doing something (probably extremely obvious) wrong?
