Why doesn't "TraShadow", work with YafRay?

Support Basics & Interface

I want to have a transparent glass for a room. But I remembered that TraShadow doesn’t work with YafRay. Is there some type of workaround?

Try taking a look at “Caustics” in Yafray…do a search here or browse around
on yafray.org. Should get you where you need to go…

//The M.h.p.e.

I don’t think caustics are what I’m looking for. I know how to use them, but I want to just have shadowless glass.
