Translucency shading errors

[fixeighted]

Simple initial test gets this result with random values. This image shows fog at 255 red and scatter pure white.
Pretty much the same errors, whatever you dial in.

I'm not sure where are the errors? If you mean the faceted look, this is expected with very small SSS radius (in your case the blue and green components of the fog color are very small). The way the light travels inside the volume depends on the geometry and the smooth normals cannot hide the fact that it is relatively low-poly. You could either add a Turbosmooth modifier to the sphere or use a VRayDisplacementMod modifier in "Subdivision" mode.

I've put some more information here (the section on low-poly geometry):

Here is an example on a sphere with similar settings to yours.

Oh I see, thanks.
I don't understand why this info in the pdf is not anywhere in the docs pages.
Makes me look dumb when posting stuff like this

I will ask the docs team to add this information.

That would be wonderful, thanks
