Hmmm. I've only checked visually, but when rendering on an image I can't
see through the text. If you get transparency I must be doing
something wrong.
I'm not in front of a computer at the moment, but I'll try and break down
my process and see if I can figure it out.
I'll let you know what I find.
Thanks,
