I found this tut in CGWorld magazine i think and then saw it on YouTube. its by Andrew Price. And as always a great job.Clear and consiese instructions. i think i spelled that right. Anyway,cool tut enjoyes doing it.Its just what it looks like in the picture. the new smoke sim and fluid sim. Some compositing,the new and exciting smoke flow force field.Dont know if i you'sed it properly but its new and i'm still learning it's functions.This is'nt an official build its from MiikaH's website, The Fried Chicken Branch.So hear you go. I love this program.Not tryin to say i'm a master i'm just tryin to keep track of things. I have so many builds its getting tough to keep everything organized.
