I never thought before that is possible without plugins like Realflow, but it is. Big thanks to
Nikolaus Schatz and his youtube tutorial, what makes cca 90% of knowledge in this tutorial. Also thanks for permission to publish and modify his idea. And its surprisingly not very hard work, so lets go...
1. We start with modelling basic shape of a water splash. If you find some real splash photos online, its something like a simple crown. Best way to get it, is start with simple cylinder without caps and some more hight segments (we will need them)
2. Make it editable and add a Taper deformer to it (select cylinder, shift+click on Taper). Move deformers control outside (or set it to minus strenght, with 100% curvature). Doesnt matter how much you deform it, something between minus 50-150% looks still good.
3. Right-click on the deformed object in manager and select "Current state to object" (or from top menu: mesh/conversion/curr...). Delete original object with deformer. Rename the new object to "4small"
If you google water splashes photos, you can see, that a bottom of the splash is in most cases like a wall of water, then in splits into smaller water drops. Thats why we need later two crown-like objects, on which we will clone water drops (and melt them together with Metaball)
4. 1st we model big crown for small droplets. Select object "4small". Swith to polygon mode. Select some polygons in rough crown shape (dont select much polygons in the lower half of the object), delete selected.
5. Switch to point mode, right click, optimize.
6. Duplicate object, rename it "4big". Select "4big", go to polygon mode, select polygons in upper half, delete them. Go to point mode, optimize.
7. Now create two water drops, just a normal spheres. Name them "big" a "small". Radius depends on the size of the crown, f.e. if the "4small" object is 400cm in Z axis, spheres should be around 10cm and 5cm in radius.
8. Create MoGraph Cloner. Drag "small" sphere inside it, change mode to "Object" and point it to "4small" object. Change distribution to "surface" and amount to cca 250. Play a bit with the seed number until you get nice distribution (its not a problem, if some droplets lap each other). Select Cloner object and add MoGraf effector Random. Turn on only Scale (under it select uniform scale) and play a bit with the value.
9. Duplicate the Cloner. Drag "big" sphere under it, and change pointing object for cloning to "4big" object. Play with seed and count parameter until you get more-or-less even distribution with more overlaping.
10. Select objects "4big" and "4small" and hide them both in editor and renderer.
11. Select both cloners, group them together and put the group in a Metaball object. In Metaball set Hull value to 100%, both subdivisions to 3 cm (depends of scene scale) and turn on Exponential Falloff.
12. Adjust sizes of both cloned spheres, count of clones and seeds, until it looks natural. You can turn off Metaball in manager between changes, this function consumes lot of CPU power.
13. The middle drop you can create easily with few spheres in other metaball and the rings on water are created with formula effector with sperical falloff on a highsegmented plane. You can also add displacement effector to plane to make it look even better.
14. Create a water material (IOR = 1.333) and add it to all water objects.
Have fun with your modeling :)
