Sailor_ed that is interesting. I was referring to volumetric light thru transparency. I tried in c5 and it didn't work will have to try that(thought I played with shadow settings.) Arcady, anytime you are looking for something specific like that you really have to check things out.I understand how important it is to you.Maybe someone can come up with some other options. Enhanced volumetric lights would be nice.I suppose if you have vue and like those effects you can port your modeling over to vue unless you like vue 5 modeling which isn't much.

No need to think outside the box....
