The particle number on my settings appear in gray, I don't think i'm able to change the number even thought i need it, how can i make it white again?

  • $\begingroup$ Is the particle system linked from a different file? In that case, you have to change the settings there. $\endgroup$ – JulianHzg Dec 31 '14 at 14:28

    $\begingroup$ This will happen when you have done something in particle edit mode, like combing or adding particles. If this is the case there will be a free particle edit button somewhere. $\endgroup$ – PGmath Dec 31 '14 at 14:34
  • $\begingroup$ No, the particle system is linked normally with the same objects on the same scene/layer in the same file. Also, i just changed 'grid' to 'random' and it changed back to normal...but then i go back to 'grid' and the settings are still gray, yet i can only change the number of particles in any of the options except in 'Grid'. $\endgroup$ – beavoru Dec 31 '14 at 14:34

    $\begingroup$ Have you baked the particle system? $\endgroup$ – Christy James Dec 31 '14 at 18:16
  • $\begingroup$ For future reference, the reason that the particle number is grayed out is that the particle layout is set to Grid. $\endgroup$ – user14089 Apr 30 '15 at 18:08

I just found the solution for it: It is greyed out when it was baked. Go to the "cache" section in the particle system and click on "free bake" to be able to edit the greyed out settings again.
