Hi!
Some people asked me how to render ionic sims with Maya, so just uploaded a very simple scene where you can just set your .ion caches and render. I'm not a Mental Ray expert at all and I couldn't make particle motion blur work, so if someone knows how to do it please post it in the forum (ionic.forumotion.co.uk)
This is made just as a render starting point scene so It's not as cool as the Houdini one, but it's not bad for a 4 minutes simulation! ;O)

So, make any sim and write the .ion caches, load this scene and set your caches in the nodes ionicEmitterPool and ionicEmitterFoam, click render :)
