FLIP - Slip on Collision Control Field

[ParticleSkull]

Hey guys,

What is the best way to use the slip on collision control field, to avoid viscous fluid of sticking on objects?

I managed to do it with the help of a friend, using the gas match field + a source volume. it works fine for static objects but not at all for moving ones. I have a project with an alembic animation and I really need to use it on the animated surface. Can someone help me?

Here's the setup in dops:


Here's it working fine with a static object. It's a top view and the red box is the sliping object:

and here the red box is animated, not working:


Not sure if this is the best way to approach it so any other ideas would reeaally help me

scene file is attached

Cheers,
Alvaro

Sup dudes, I got some pretty awesome answers on facebook. Didn't got the time to check it properly but I know that the scene file is working.

Thx to Jason Slabber for the file. It uses a SOP Scalar Field and looks much simpler than what I was doin'

"one good very efficient way is also creating a gasmatchfield in dops using surface as reference and name it slip... then create a gasvop and create some noise there... you can also animate it, bring geo and do magic tricks"

"it will be very efficient because just creates the field where you have flip... and it's resolution will always match your surface field resolution"

I didn't got the time to try this last one but looks really cool

Hi.....
I have two sources in a flip solver and I want to have different slip to each one of those sources, how that's possible?

[tamagochy]

You should create that field in sop and import to dop

have u any hip file for learn.................

HI,

 

Does anyone has idea to control slip field over the age of same flip particles, I want to control slip over the age of viscus fluid.
It should be not not moving at all initially and over the age it will.

Thank You

hi Skull, 

This method really help me alot when I'm working on my scene. Thank you for sharing what u could learn from FB. Can I ask the name of that Fb group? I would like to join the VFX world to do more cool stuff like you did.

Thanks,

Hi Doanh, I don't remember and I'm not even on FB anymore. I used to get anxious and stressed out there seeing moronic poeple posting opinions and fake news about everything so I just left and nowadays I feel a bit happier.
