In the Colliders module we can select which objects we want to work as colliders for the particles.
We will be able to configure different values such as Stickiness, damping, friction... and get a much more realistic result of our fluids. We can add single objects or add collections of objects. We can also convert an object into an Outflow to remove particles.
In addition we can animate all its values to be able to have complete freedom when creating our simulation.
Let's see some examples with different values in our colliders.
Friction 0.05
Friction 0.2
Friction 0.8,Stickiness 0.1
Being able to set different parameters in our colliders is really useful, as it allows the same fluid to behave in very different ways in each object, making the simulation much more realistic. The behavior of a fluid is not the same on every surface, it depends on its roughness, composition, materials, etc...
