Hi, I have just started with OpenSceneGraph. I am working on a project in which i need to capture frames from a video source and render them as texured quads. I need to enable transparency on these textures but my problem is that frames i am grabbing are in RGB format so need to add an alpha channel. My research told me if i set texture internal format to RGBA OSG will create an alpha channel for me. Now problem is how do i insert value in that alpha channel at runtime. I only need one alpha value that will apply to whole texture.
I cannot use shaders in this for some reasons. Please Help !! Thank you!
