In the materials slot their is an "assign" button, is there anything like this for particle systems? But more specifically is there a way to assign a different material to a different part of a mesh. Now finally how do I keep a particle system off part of my mesh entirely? For example: bird I want the blue and black to be the same particle system, but different colors, the orange to be a different particle system and no system on the legs.

  • You can use vertex groups or weights. –  Jul 15 '16 at 22:45
  • @cegaton could you explain a little more, I see the vertex groups tab under particle systems and I have vertex groups on my bird(mainly from the armature) but I don't know what to do once there – Unnamed Sentient Being Jul 15 '16 at 23:07
