2 objects + 1 floor + 1 emitter + magic dust + abracadabra...
Tadaaa

Still needs work.

BTW has anyone tried this?

... one object seems to be a dielectric with a low abbe ... mystery ...

Something like Baboule and Micha said.

the bottom layer is a silver metal material and the top layer is a very thin dielectric with very low abbe (30), refraction 1.518 and a bump map.
The bump map was originaly made in Illustrator. It is made of 1000 cocentric circles, the small 3cm and the big 12 cm, the thickness of each line is 0.05 pt. Then I opened it in Photoshop at 1200 ppi and created a 92 MB file and used it as a bump.

I will try to model it with natural bumps to see how M~R will handle it.
Just for fun.

It seems from this test that was inspired by sam7 (thanks sam7

), that anisotropy can be made with certain bumps.

Cool
That seems to be a really fine detailed bump!!

I'm running more tests on this subject now, but I think I'm not getting a rainbow effect. It's just the low abbe that gives out the scattered colors and not dispersion.
I'm not sure.

I'll post more stuff later...

Very good tests!! I'm trying to recreate anisotropic effect, but no way by now. I think you have find the good method

To be honest, I'm quite unhappy with the effect. Even though it exibits the power of maxwellrender to cope with HUGE maps and the anisotropic effect is very nice, it doesn't show any sign of dispersion.
This may be due to my bad lighting or texturing of the models.

If anyone has an idea I'll be glad to hear it.

Thanks for the comments guys!
