Thanks guys,

Nick, I like the idea of blending the top surface with the rest in comp. 
I'll continue in that direction I think but I'll have a look at what 
Robert sent but for now the sidefx.com website seems to be down. I'll 
let you know what I've found on your thread Dominik.

Cheers

Francois
