Now we have everything. If we click on Action we will see that the particles are not interacting with the geometry. To make that happen, we have to go to the Scene Tree. In there, add everything that interacts with the particles. In this case, the glass, the plane, the gravity daemon and the ~volume daemon.


IMPORTANT: Every square on the grid has 1m x 1m and the scene scale is very important for physic calculations. We might need to change it. In my case it's 0.2 when the default is 1. Try not to use the exact scale because the object is too small and realflow has some problems with that.




Before we click on Action, let's "tell” realflow to save our particles. To do that we go to the Export Central and we put a little check on the emitter.
