[osg-users] Single channel image

[Tony Vasile]

I trying to render a single channel image on a Billboard but I am having no much luck. I'm expecting to see the black parts of the image to be transparent but I am just seeing black. The white parts of the image are as expected. I have tried using 
Code:
setInternalFormat(GL_ALPHA_8)

, but all I get is the colour of the Billboard that the image is rendered on. Does anyone have any ideas on how I get this image to render properly.
