...Which for some cases is close enough. A single "ripple" can be simulated as an expanding circle of displaced material. Obviously you can't get the damping oscillation of a true surface out of that! A splash, also, can be as a first order approximated as a fountain aiming upward and outwards. If you can manage collisions so particles are sent upwards and outwards, do they not resemble a splash? Remember, metaball surfacing is allowed here, meaning you can smooth a "skin" over any group of particles not spread too thinly. Obviously you are no more simulating a liquid phase than you are a solid phase. But 3d is all about fakery, neh? At this point in time, which would be the best option for a Carrara animator wanting to do a simple droplet effect? A) Dump Carrara and buy Lightwave. B) Put the project on hol and wait in hopes that the next version will have the function you want. C) Paint in everything by hand frame by frame. or D) Fake up the best approximation you can with animated metaballs, particle effects, transmaps, formulae objects, and anything else that you can dream up.
