Nuke/Vray exr float info

Cool, 16 scanline was the one I tested with this morning, so Ill now try 1 scanline and see if its better.

It only seemed to be about 20% quicker.

edit:
1 scanline seems to be slightly quicker than 16, and defiantly a noticeable speed improvement over the default tile out of Vray.
