Interesting.  Thanks again for another great explanation and assistance!

Ah, got it!  Thanks BB!   Excellent explanation.  Initially, I wanted the effect to be cast on a glass object against a black background.  I understand now that this may not be the applicable method for that type of scenario.  But it's still an awesome shader!!   Thank you!!   BTW, is there a particular type of lighting you think works best with this effect?

Fair enough BB.  Here's the result.  What am I doing wrong?

Thanks RedPhantom, I changed the refract colors to black but it still renders the same.

OK, I'm up to date with SR5.  Unfortunately, I'm still getting the same results.  Here's a screencap of my set-up.  I'm using a box primitive as before.  Raytracing set to 4.

I'm using Poser 2014, but I might be an SR behind.  I'll start there, thanks.

Thanks BB!

Is there a way the effect can be applied to edges only just as you have in your render?  Obviously I'm doing something wrong (see below) but I can't figure out what.

BTW, my raytrace is set to 2 (although I've gone as high as 4 without improvement); pixel sample set to 3.  Lighting is 3 infinite and 1 diffuse IBL.

Thanks for the link and suggestion Miss Nancy.

BB, that's awesome!  Yes, that's what I'm looking for.  I know you described what you did, but can you also please post a screen capture of your set-up?

Thanks!

Thanks very much Heddheld!

I'm very sorry for your loss.  Take care.

I found a picture for reference.  Does this help?

@BB, no, I'm not after the green edge.  I really do mean prismatic.  Unfortunately, I don't have a reference photo at the moment but will endeavor to find one.  In the meantime, what I'm after is the rainbow effect when two adjacent glass edges are at an angle and the light seemingly refracts on the edge.  Perhaps a useful example would be a glass award with edges that refract when turned to the light. Very similar to cut crystal.

Hmm, I see what you mean.  Thanks Laurie.

For some reason, I thought I saw a render of a diamond complete with prismatic refraction.  Must've been my wild imagination.

I was looking for the rink as well.  Are you making yours available Heddheld?

Alternatively, can anyone advise how to make Dr. Pitterbill mimic-ready?

Thanks again.

Even though my default browser is FF, once I was able to revert back to IE 10 all my Poser issues were solved.  BTW, I'm using PoserPro2012.
