I attempted to create a dripping effect like this:

On a curved surface using this technique, however the long particles don't conform to the surface, looking very unrealistic (it looks particularly bad on sharp corners).

Is there another way to get this effect, or a way to use this technique on a curved surface?

In other words, I want to make the particles stick to the surface (while still being able to slide freely) and somehow leave trails behind them.

  • $\begingroup$ @sambler Is there a way to snap to the surface automatically? (shrinkwrap?) Sculpting each one seems incredibly tedious.. $\endgroup$

  • $\begingroup$ I can't think of a way to make it work automatically. Shrinkwrap would pull the entire droplet flat, vert groups would pull the back and leave the top way out. shrinkwrap a flat piece to the surface and then displacing would not create good looking drops. None of these help with a particle system, only after it was applied. Either sculpt or proportional edit in edit mode to an applied particle system is all I can think of. What we want is a shnkwrap that has a preserve volume option, allowing the closest edge to shrink down but still prevent the other sides from collapsing. $\endgroup$

  • $\begingroup$ @sambler I guess in that case I will just try and sculpt the drops from scratch.. Thanks anyway. $\endgroup$

Sardi Pax released a tutorial for applying metaball particles as raindrops to glass, I believe there is no reason that prevents his method from being applied to a curved surface. If this method is used instead of sculpted particles, they should conform to a non planar surface. http://www.youtube.com/watch?v=RDte-IzvHlg
