Arrg! Every time I sit in the theatre I want to do the smoke/dry ice effect.

The floor finish is the BoisJaune wood texture in a brick pattern and I'm not
using attenuated by media. I'll post a render I'm doing just now, later.

Thanks for the post, again, I'll experiment tomorrow. As for visual perception
it is funny what you think you see. I am sure that when the eye sees an object
the brain remembers it and when it looks at another object, in RL the brain puts
together a composite picture. Like rendering different parts of the view with
their own optimum settings
