RE: Shape attracts fluids
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.

RE: Shape attracts fluids
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?

HOT for Maya
Hi reviving this topic as its HOTOcean related, hope thats ok?
I needed to do some ocean work in Maya and downloaded the latest version of HOTOcean and installed for Maya 2016 but I have a major issue where the deformation keeps increasing in Y axis once I press play and no matter what I do it just keeps moving up on every key press on the transport buttons. Anyone else have this issue? I have emailed Nico also about my issue.

After pressing play.

Attaching an existing nCache sequence

I just noticed what seems to be a bug in Maya 2017 & 2017 and took me ages to realize what was causing it.

The annoying issue was basically that I created an nParticle system being advected by a fluid, caching out the sim worked fine but on deleting (Keep files) the cache the issue was with trying to attach an existing cache where I kept getting the error:

 

"// Error: file: C:/Program Files/Autodesk/Maya2016/scripts/others/doAttachCacheArgList.mel line 65: Must select either nucleus related geometry or fluid objects that the cache will drive // "

 

I could create a new cache for it but just can not attach one. If I created a fresh new nParticle I had no problem attaching a cache sequence.

So the difference between the two had to be found and the reason was not obvious but the Fluid being attached as a 'field' or not made the difference. On disconnection of the fluid as a 'field' in the 'Dynamic relationship Editor' I can now once again attach an existing cache, but if its still connected I get the error.

My question is I converted and exported the sequence with the name "Test_####.vdb" and each frame played saved the coresponding number, but in trying to read the sequence it only reads one frame and not the sequence what have I done wrong? How do I get it to read a sequence? Im using 2016 version.
Also I was looking at the video of converting VDBs back to Maya fluids but there doesn't seem to be the node thats in the video 'BE VDBToMayaFluidNode'?


Figuired out the sequence playback. But curious still as to where the VDBToMayaFluidNode is?

Strange. I think I'll start a fresh to see if it does again.

Hmmm seems another issue has arisen. At boundary intersection the surface emission now is only on half of the selection for the first frame of emission but then the full amount of faces emits.

Awesome! thanks that sorted it, adding the faceNum [0] was the bit of the puzzle I was missing so to speak. thanks for the heads up too on the missing bracket in the nParticle runtime.

Hi sorry for the delay just saw this reply now, here is my set up and just can't get rid of that one lingering face and get errors with ourouk's fix.
