Soap bubbles and glass?

Hi every one,

Ok so soap bubbles and glass both do this thing with light that causes a rainbow that contours to the shape of the object, and also it seems to follow the specular light.

I have seen this done in blender but how would you go about it?

spec ramps might be useful. i don’t know how you would get the swirly effect though. maybe a marble tex with colorband?

A marble tex with colorband.

sounds good, would happen to know any examples?

Have a look in the Blender Material Repository.

Wow thanks!

This is what I’m talk’n about, I’ll study these so I can make my own just as I need.

Thanks everyone!
