Heya,

As the title says, I was wondering if anyone had any tips for controlling surface adhesion for MPM water so it clings to the underside of surfaces at small scales? I want to simulate an ink droplet clinging to the underside of a small rod like a pen but no amount of setting tweaking is getting me any closer. Am I missing something critical?

Are you only tweaking the water source settings? The colliders have some settings that would also affect this, I think...

I've tried increasing various settings on both the source and the collider, including the friction and stickiness of the collider

If the main settings ain't getting you there, you can experiment with a viscosity/stickiness (??) attribute transfer from your collider. Kinda cheating it to get the result you want... Can't push it too much or it'll look funky though.
