Blender Fluid Sim, Realistic Vomit? I'm trying to use the fluid sim to create a vomit VFX shot for some live action footage I've got. But I'm struggling with getting it look the way I want. So far this is what I've got: 



I'm relatively happy with the way it lands on the floor (except for the jittering), but I'm wanting to improve the way it falls. Currently it just flows too smoothly, where as I'd like it to be more like this: 



So it has more of a 'spraying' and forceful quality to it, where the diameter starts narrow at the source (The mouth) and then it spreads out the further from the mouth it gets.

Any suggestions?
You will need to use particles in Fluid mode, perhaps metaballs if you have the ram for it. This will give you the blobby appearance then render with motion Blur. You'll need to duplicate the particle settings and emitter for blur.





Use vector blur but you can only use Blender internal for that. Make a normal object particle duplicate of the metaball cascade, on a separate layer. Apply this vector blur to the metaball layer.





In the compositor use the 2nd render layer to drive the vector blur.



Results with and with out blur, change vector object  scale to suit blur.



You may have to adjust the particle life of the vector object so that you don't get blurring of the floor.
