need sticky liquid - KBTIT_ - 09-04-2024
How can we describe a very sticky liquid, like oil?
For example, something that takes a very long time to fall when it hits a vertical wall.
First, I set Viscosity to 2, using this page as a reference.

There was indeed a change, but it is still not enough.
Next, I changed the Gravity of the Buoyancy and Obi Solver so that it takes longer to fall.
These are fine if only a little, but changing them significantly can cause undesirable visual effects, such as slower falling speeds.
Therefore, I would like to know if there are any other parameters other than these that would affect the stickiness if changed.

Hi,
Viscosity only affects how viscous the flow is, but doesn’t have any effect on how sticky it is when hitting a surface.
That is controlled by the collision material’s “stickiness” and “dynamic friction” parameters.

Also, see the ViscousFluid sample scene for an example of a fluid that is both viscous and sticky.
