Thanks for sharing that Matt, this will be a big help, ive been a bit "blah" about Apo lately, cant seem to make anything i like. That has resparked my interest a lot! :) Oh and on the subject of rendering... i used to render my flames in UF, i still do if i find one i particularly like. It does take an enormous amount of time, and cpu power ( if your pc is a little old like mine ) but i find it smooths them etc just a little bit more than an export. All comes down to your own personal preference though :)
