Upon setting up a Specular box for atmosphere/haze in another post, I accidentally ticked the 'dispersion' box and noticed this:
Dionysiusmarquis wondered what it would look like in animation, so I set this up (super quick) to test. Sorry about the overexposure:
In the animation, I did not use SSS in the 'haze box', but simply turned on diffraction to get the effect to not have a massive increase in rendertime. 17-24 seconds on PMC! Setup was dead-simple: Specular material, turn reflection off, turn dispersion on, set IOR to 1. Fake Shadows ON.
Not that I am a huge fan of CA, but could be useful for certain effects...
best,
