Photoview 360 error

Hi,
I got this error msg when I tried to use photoview to render myassembly.
I tried to alter the render quality, and there is a prompt

Subsurface Samples
This only applies when Subsurface Amount and Scattering Distanceare nonzero.


Does anyone know what this mean ? and more importantly, how can Irectify it ?

Thanks
