Thanks MartybNz!

I had been looking at this but was hoping for a solution within Mantra.
But thank you very much for the explaination of how to set this up very handy!

Yeah that was what I had found but the scene I actually need to render is hugely complex and has hundreds of bits of geo like this so as you can imagine having 16x16 pixel samples is very expentive being about 10 hours or more a frame.

If anyone else has any tricks to get around this they would be greatly appreceated.

Also here is a render. Had to zip it as i don't seem to be able to attach an exr but you should get the same thing hitting render on the scene file anyway
