@amethystpendant here's the full shader:

and the Compound Metal shader (which I think owes attribution to @bagginsbill , perhaps?):

So the shader is fully metallic/specular, hence the black Diffuse_Color. The connections to PoserSurface:Specular_Color are just for SreeD preview purposes.

Clothing figure is the same SwimSuit for V4 by Mada/FaeryDreams, but with different transparency/hem maps of my own devising.

If you want more subtle iridescence effects, like mother-of-pearl, knock back the saturation in the Reflection_hsv node to, say, 20% (0.2) and set the Diffuse_Color to white.

IIRC, iridescence derives from multilayered materials acting like a diffraction grating and reflecting different wavelengths at different angles. The high multiplicative factor in the Hue channel of the HSV node simulates this when fed by the Fresnel_Blend node. Play with any of the parameters and see what effects this has. You might be able to get results which stably show different predominant colours than the blue-green this shader does.

@anomalaus That is wonderful, thank you. I don't suppose you could let me have the MT5 file as I'm bound to mess up some of the plumbing. If I had that I could add it as a material applicable from an EZSkin3 pluggin. I don't need the actual trans maps.

@amethystpendant here's the MT5 Iridescent Sequins HiCut Hem.mt5
I've cut out all the personal folder identifiers, so they're just generic file paths. Trans and bump maps are not included.

Thank you so much, as soon as I have my hair shader plugin out (hopefully today!) I'll start having a look at this :)

@anomalaus Thanks for this, I was quite right, I would have totally screwed up the plumbing :)

I've now extracted the shader part from both the Suit and the sequins and am playing around with the settings, colour, ior etc to get a better understanding of what is doing what, or at least the effect, as I'm unlikely to get the maths behind it all!
