Quote - 30 samples doesn't take that long to render. I was doing test renders with just James (the clothed figure, changed his shirt to red), about 600 by 400 in size, and it was less than a minute to render.

Rendering with DV=0 and SV=0 won't save any time. Even if it did, compositing in post would be impossible - you need to add the Gather effect, so you'd have to make everything else BLACK in order not to double it, which then would make it Gather nothing at all.

Yeah I see what you mean about compositing is no good here ( didn't occur to me at the time). I did a gather-test render yesterday with 30 samples and final render settings and it took about 15 mins.  My machines not too fast though. It took about 5 min with just primitives thrown together to look like a head and neck and a shirt. 15 min is a-ok with me but if I had a full scene that takes an hour or more I think I'll pass on it. I need to play with this some more thanks for helping out I really appreciate it. :)
