I’ve been trying to create an animation with an object falling into a glass of water and making a big splash. Thus far, nothing good came up with fluid simulation (I’m currently using Blender 2.91.2).
I have an extruded cylinder mesh for the water glass, a mesh for the water in the glass (which is a duplicate from some faces of the glass with a fill on the top), and a UV sphere keyframed to fall down into the glass. All within the usual domain cube covering everything. I’ve setup the sphere as an effector, the water mesh as a geometry fluid. As for the water glass itself, I didn’t know what to choose… anyway, neither seems to work.
Once it’s baked, the sphere falls into the water mesh, but then it’s just “swallowed” lifelessly by it. No splash. Diffusion and mesh are checked with default values. The number of samples of the bake does not change anything. On the other hand, if the water is not contained within another mesh, it works out fine.
I’d like to find out what I’m doing wrong. I’ve been reading books and watching tons of Youtube videos (notably this one Quick Water Simulation (2.80), but it doesn’t work the same with 2.91.2.
Thanks in advance.
