This is in Bryce4- I have a scene, and I want to have a streaming light effect coming from behind some trees in the background. Unfortunately, when I use the spotlight and set it up- nothing happens, except that the render time goes up significantly, even though there is no visual difference. Also, I have noticed that if I remove a radial light then the spotlights are visible; thing is that I need the radial light and also the spotlights with the streaming light effect. Any ideas?
