As the wing is behind the ring, is there a setting to keep glow from splashing forward to unrealistically effect another object? As it is it looks exactly like what happens in when you glow a foreground sprite in 2D

I don't think so. I think Vue's glow is more like a 2D plugin, especially since it's an after effect which isn't applied until after the render is completed. I'm still trying to figure out what "glow behind objects" means.... I don't really like Vue's glow feature much, especially since you can't resume a render of a scene with any objects in it having glow.

Try unticking 'glow behind objects'. This does not affect the little camera preview window, but does work in renders to main view and above.

thanks for tips :) ..guess its like many things - gotta learn abuse before you master use.
