I tried the Veloute stain glass tutorial from the Inagoni site and noticed it used a glow for the stain glass to simulate the light making the colors brighter. I turned off the glow and rendered. The stain glass was very dark. It still used transparency to let light through it though. Then I dragged the transparency attributes to the translucency channel and turned off transparency for the stain glass. Here is the render.

Very interesting. I will have to check it out. We really need the volumetric light improved, badly. I hope more people tell them so they realize it's importance. I know they hear about uvmapping tools enough. Here's hoping.The glow channel appears to be equivalent to luminance. I think it gets under utilized alot.

Interesting: have to play with that a bit. Thanks.

Here's a similar test I did a year ago, I used a gel of the stained glass in the light and lined them up. This is one reason I have asked for a parallel light so that something like this could be done easily without having the rays widen out. The new translucency makes it a little easier, but obviously deosn't solve the volumetric problem.

Yeah, I was playing with gels when the last discussion of volumetric limitation was going on. That looks good, not really 100% accurate but, much better than other attempts I have seen.
