Pretty much what the title says. Where do I actually find this if I want to play with it for a bit of fun? I just updated to 1.6 and checking out all the extras. Saw the psycho sampler in the notes but im not actually sure where it is?
In the Render Setup, open system settings and enable Devel/Debug options, then head on over to Performance where those settings will be shown and you can choose the random sampler there. IMPORTANT - it is not intended for production use, so you will want to be sure to return to the default sampler once done (5D High-D Stratified). Hope this helps!
brilliant thanks, i thought it might have been hidden since its not for production use. Just wanted to check it out.
Most welcome, have fun with it 
Will be interested to see any results you come up with!
