Have you tried getting the effect you're looking for with spotlights, and the colored shadow projected onto some actual geometry (instead of the DAZ ground shadowcatcher)? My only guess about what's going on in your renders is that it's a problem relating to the lighting HDRIs and ground/shadowcatcher rather than the shader.

I tried turning the 'Caustic Sampler' option on and was disappointed that it didn't look any different to me.

These tests are with default render settings. Also, here are the settings for the blue glass shader, shouldn't be anything surprising there though. The third image is the same as the second, but with the sun enlarged to soften the shadows and the blue projection. Here it is lit with an HDRI, and then on a white plane with sun/sky for light. I'm using a 1 foot diameter sphere with the Glass - Solid - Light Green shader, and the only change to it is that I made the transmission color a vivid blue instead of light green. Even if it might “look” correct when directly looking at it, the actual physical values for the sun might be way off, something that is unfortunately very very common for a lot of available HDR environments.Hi Andy, colored glass is working for me on a sphere. So the only explanation i can give you for your problem is that simply the sun/environment that you use is way too dark. Iray actually was and is used for architectural visualization a lot, one huge example being the NVIDIA headquarter itself (see ) where it was also validated and compared to other professional light simulations in the process (see same page). Are there any plans to improve light bouncing for indoor rendering? The workaround is to work with a lot of ghost lights, but these consumes a lot of time. While 3Delight was essentially the original engine used in Daz Studio, the addition of Iray has opened up many amazing possibilities for users.

And figures skins get quickly much too dark, too. When You Should Use the Iray Render Engine In Daz Studio, you have the choice between two render engines included for free: 3Delight and NVIDIA Iray. In-door scenes are much to dark, even if the sun goes directly through a window. The light bouncing for rendering in-door not optimal.
