Thanks for the clarification. It appears as though there is a bug then. I have filed a bug report that highlights this issue.

Cheers,

"replace" means "blit the image pixels as is", no matter what the alpha value: if a pixel is RGBA=(1,1,1,0), it is written as is in the frame buffer

Related to all of this, if I specify a blend mode of "Replace" for my billboard's image, should that image be rendered now matter what its alpha value is (including an alpha of 0.0) i.e. does "replace" effectively mean no blending should occur?

If replace means no blending then I think there's a problem. If my image has an alpha of 0 then it won't show.
