Hello
I have a cube with Specular mat on it.
I try to have transparency in the alpha channel to composit with after.
I try different option- fake shadow, Alpha Channel, alpha shadow.
I always have a plain alpha.

In a second time could I have a " hdr Map" for reflection in the glass. And get the alpha with transparency.

Thank you

Alex

AFAIK and according to my previous experience, Specular materials are (or have to be) always 100% in alpha.

Similar (but not the exact) discussion is here : http://render.otoy.com/forum/viewtopic.php?f=36&t=34683

Thanks
I will go check.
