Sorry for the delay......

I have tried with virtually all the rendering settings including Custom, with anything from 200 to 10000 pixels (proportions constrained).

I have tried quick render / 3D software render / hardware render / altered buckets etc and I still end up with sh.te quality images / small files...or none at all as the render fails after an hour or more!

It is not as though it is a seriously complicated image either....it is just a customised human form that I am using to get used to how 3D progs work.
