Just tried it with a lower profile ATI HD 4830, and it didn´t solve the problem… maybe you know other magical numbers?

Thanks Seb!
That´s right, in fact part of the problem was that I wanted to get the attributes into the same volume ops:

I didn´t know how to bring sop attributes (in this case “rest”) from the particle simulation to the volume that the IsoOffset generates. It´s already solved. I´ll post the link to the posts that helped me tomorrow as I can´t find them right now, they are very interesting.

Is it possible to use rest position with an Iso Offset SOP? So that the billowy smoke shader can use it for sticking the noise to the volume that the IsoOffset node generates.
