Decal Disappears when Rendered w/Ray

I’ve got a glass object that I need to put a decal on.

I’ve got the png with alpha placed using the ‘Map Input - Object’ method.

When I render without Ray it’s exactly the way I want but the glass is no good.

If I render with Ray, the glass is great but the decal is barely visible.

What am I missing??

I’ve tried many variations of the ‘Map To’ panel with moderate results . . . .
The png is white on transparent, ‘Map Image’ is ‘UseAlpha’ and ‘Clip’

Help as much as possible and maybe attach a blend file? (Go Advanced and paperclip to attach blend)
