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?

A quick Idea would be to go to Corel and look carefully at thier tutorial on the new Light Lab. I am sure it will not answer every question but it just might give you the right direction. Be pleased! Lightpen

And to see the new light lab you would/could try a copy of the scene in Bryce 5 demo version

Brycetech has a great tutorial on streaming lights. Maybe this will help.

There are a lot of things worse than dying, being afraid all the time would be one.

Heh, thanks. I did not notice that tutorial before, even though I regularly visit the site.

How about adding a really faint dust cloud, something light for the light to reflect from. In actuallity that's what causes the light strams in the first place. Dirt in the air. Hope that helps.

Bryce volume light has a rendering error. It happens when you have a volume light and another light (non-volume). If a shadow generated from the non-volume light hits on the volume light that volume light part gets cut off.

So- I should disable 'Cast Shadows' for the non-volume light? And, thanks for all the help people. I think I might just add the streaming lights in PhotoShop-if I can find a tutorial.
