Applying filters to parts of the scene graph?

Is it possible to apply a filter to only parts of the scene graph? I have a few spheres I want to glow but when I apply the filter everything glows. I think one way to do this is with textures but I haven’t made it that far yet.



If it’s only spheres you want to glow, I think the easiest way would be to use billboards.

I just want to say that while this might be sufficient, it won’t give the exact same effect as a true glow filter. With a glow filter, the glow from a partially obscured sphere will bleed over onto the object in front of it, which won’t happen with a billboard.

I’m pretty sure that applying glow to only parts of a scene graph is possible, but I don’t know the specifics myself.
