Subdiv glossies buton

I think I found a bug.

When in use the Auto button makes glossies Subdiv refraciones activated, since the subdivision is over and I have not activated. As a result, semi translucent glass appear white.

I did some tests and clearly when button is on auto Subdiv leaves glossies this parameter, Trace Refraction and Reflection on the Options tab void. This happens with most of the materials, not all.

Yes, I have installed this vercion. Problem is that the slate already reslviste but this is another.

I'll try to explain better.

When you render with solidrocks with button stops auto glossies subdiv materials Reflections and Refractions without Trace.

Got that?


Greetings ...

PS: you do the best you can.
It is very complex to fix this?

Let me know if you understand that I do not speak of the previous problem with slate but another very different.
I need you to tell me if that I raise a problem for the new update.
