Im using the fresnel attribute but when I do a best render the fresnel effect dose not render. How do I get the fresnel effect and other things like SSS to render?
Thanks

in ZB4 they added Best Preview Render or simply BPR
It is very different from Best Render here are some differences:
Best Render-
No antialiasing (requiring you to render at double resolution and size down)
No Subsurface Scattering
No Ambient Occlusion
BPR-
No colored lighting
antialiasing
Subsurface Scattering
Ambient Occlusion
So basically if you want SSS to work you have to use BPR, unless you render in passes, then you can render your SSS in BPR and everything else in Best Render then composite them together in something like photoshop.
