#decal question
I'm creating a perforated ribbon (curved flat plane) which is suspended in a
room. I've made a bitmap of the perforation grid consisting of a white
background and top and bottom border. When I map this to the ribbon face and
render my white perforation pattern renders black, not transparent. The top
left pixel is definitely white. I'm missing something obvious here (I've done
this successfully before) but can't figure it out today. Any help will be
greatly appreciated.
Thanks Harold
