I've found tutorials for both 3ds Max and Maya on how to create lava. However I couldn't get the lava to work in Maya, it required two emitters in one container which I've never done before, so when I tired it the particles stopped showing. So I will try this tutorial again on a later date in my spare time.
The Max tutorial though was a good one, I did everything it said and it works, although it needs a little tweaking, but at the moment it’s only for tests as I don’t think I’ll be using this kind of lava in my final clip.
