I am trying to achieve a scene where a cup of glass covered with droplets. I'm using particles system and a group of droplets from separate layer, to make it possible, but I can't get droplets appear with correct direction. I was wondering what kind of settings should be done to fix this problem, please see the screenshots below

false oriented droplets droplets group particles

  • I have tried changing the positions of each droplets in the group, but didn't work
  • I have tried changing the rotations under the particles but couldn't reach a good result

thanks for your help

  • $\begingroup$ Thanks for your prompt reply @gandalf3 ,I have tried to change things according to questions you directed above, finally I can get the droplets in correct direction but this time they are not covering the surface properly as shown below evernote.com/shard/s96/sh/a5e33412-1c30-480f-b85b-48efbe79d611/… sorry for if I skipped something which has already mentioned but I really cant figure out what causing the problem and how to fix it $\endgroup$ – ideorium Jan 13 '15 at 10:09
  • $\begingroup$ Try using Velocity/Hair as the initial rotation. If that doesn't work, is it possible you could upload the file? $\endgroup$ – gandalf3 Jan 13 '15 at 10:26
  • $\begingroup$ ok, tried the velocity/hair but it didn't work either, i'm sending the file, can you have a look at it please? thanks we.tl/3PZ39DCGHj $\endgroup$ – ideorium Jan 13 '15 at 10:55
  • $\begingroup$ Ah, remember that when rotation is enabled in particle settings > render the objects should be aligned with +X (yes, it's weird like that). If I rotate the droplet objects 90 degrees on the Z it works as expected. $\endgroup$ – gandalf3 Jan 13 '15 at 11:40
  • $\begingroup$ YES! :) that worked, thanks a lot for your help $\endgroup$ – ideorium Jan 13 '15 at 13:19
