I see now that you mention it just before that section :D Missed it completely, or maybe I didnt understand that I should do it then :) Now I might be able to do some smoke for my airplane crash :) Going to comp it in live footage for a school project so we needed the particles to render with mr for the fg-pass :) Cheers for a great tutorial! Will be sure to follow your future posts and dig around in the old ones!:) Hi and thanks for the fast reply!

I'm glad you found something useful in my blog. The attribute "timeSpeed" does not exist by default. I created "timeSpeed" and "frequencyMult" as extra attributes that I could use to control other parts of the shader network (a bit like adding variables to an expression). I often do this so that all the attributes that I want to be able to tweak are in one place. I mentioned it very briefly in the line before the section titled "Hooking it all together". I can see how you might have missed that, especially if you have only been using maya for a short while. You can add extra attributes using the attribute editor in the menu "Attributes|Add Attributes..." and in this case they are both floats. I have not tried the example scene in 2011. Let me know if you cant get it to work and I'll take a look. Hi Johan. I'm glad you found something useful in my blog. The attribute "timeSpeed" does not exist by default.

Im currently trying to some smoke and render it with mental ray. So with a quick google search I found your blog and this post. Awesome! Will definitely follow it :) Now to my question. I managed to follow this guide all the way up to where Im about to connect the "volumeNoise1.timeSpeed" -> "mulTimeByTimeSpeed.input2X", the timeSpeed attribute isnt in the list! But when I open up your file is sure is there. I've only used Maya for 6 or so months and could really use some enlightenment on why its not there.. Im using Maya 2011 by the way! Cheers on a great blog! Hey David!

The hypershade snapshots are composited in photoshop as you suspected. I wish there was an easier way though. Hi matt. The hypershade snapshots are composited in photoshop as you suspected.
