Hi,
I looked at the demo reel for Phoenix FD 3.0 and the new 'Follow Path' field impressed me, and the 'Attract' force got me very excited but there is no immediate chance of getting PFD 3.0 so I was wondering if it is at all possible to set up with Maya fluids and SOuP nodes?
   I am very much still learning the wonders of SOuP and have some way to go and cant figuire if its possible, having looked at the flamethrower example with particles acting as a force influence I thought it maybe, and could be taken further to create a true 'Follow Path' field like in PFD 3.0, and the one I really need right now is 'Attract' to a mesh for a shot Im doing.
   In the shot I need the fluid to rise as normal from a source and then form a mesh shape above the source, hold the shape then after which an object passes through effecting the fluid smoke and the fluid acts again as normal with boyancy and velocity swirl,  andissipates. I have thought for now to break it down into seperate parts and vdb the fluids then merge the vdbs but I would love to know if I can truely attract to a mesh and control the amount of hold on the shape. Can anyone more knowledgeable with SOuP enlighten me?

bifrost does have motion fields to do that...

All this seems more than doable.
If you have reference videos - post them here. This will narrow the scope of what you are trying to do and we can help faster.

It's my test. Bifrost the pyrotechnic solver can do it

As far as examples all I have that perfectly capture what Im after are in the 'New Fields' section of this PFD 3.0 demo


I have tried the follow path method here
but still not getting results id like as in if my path has too many sharp angle turns the fluid doesnt follow well enough, I guess velocity in one direction is pushing to hard for another direction to pick up?

ZC - the Bifrost method for forming a shape seems exactly what Im looking for can you share a scene setup example? I would though if possible see if same thing couild be done with SOuP and Maya fluids.

Thanks for the replies guys.

Fallow path can be achieved without SOuP - just use the curve field in maya. That's all.

To conform maya fluids to mesh shapes you need the pointCloudField node. Apply it as regular field to the fluid, connect to it mesh geometry and it switch it to swept geometry mode + radial mode and that should get you going.

The Bifrost has a dynamic field that you can use to achieve this effect.
