All the same up to this point, just add the caustics statement as 
here.  You're using photons aswell, is that what you mean?
Just noticed the photons. But this should add ordinary caustics. 
You've got ignore_photons in there, so the object will ignore the 
photons and there fore not get any caustics from the photons either.
hope it's of some help.
