Steve you're a genius! I didn't really understand what I was doing but had a fiddle with all those (previously undiscovered) 'tools' functions in UV mapper pro and it seems to have solved the bad media problem (I had a few facet and vertices problems)_ My only problem is that small parts of the model look transparent in the poser preview (it renders ok) Does this mean the facet normals are round the wrong way?_ I guess if so I'll have to select them individually in UV mapper and switch them. I'm going to have to do some serious homework on UV mapper_ I hadn't realised it did all that problem solving!!!! Look forward to Lobster thermidor on the Renderosity menu!
