Fresh Effect: Blender Boids Particles Tutorial

Level: Beginner



  • In this Blender boids particles tutorial i am creating a particle animation, forming the word “fresh”.
  • All letters are bezie curves, lying on separate layers, with a goal effector on them.
  • The particles are using a boids system with settings to separate from each other.

First I added bezier curves and shaped them to form the word “fresh”. I put the letters on seperate layers, so that the particle systems don’t interfere with each other later on. Then I added a plane for each letter, scaled it and moved it underneath each letter. The plane must be on the same layer as the letter. Finally I applied the same particle system to all planes and enabled force field in the physics tab for the bezier curves. I also set the z gravity in the scene properties to 0,1.

The settings for the particle system are:

The settings for the force fields are:

For the best result you have to play around with the “strength” and “damping” values a little bit. A strength amount between 4 and 6, and a damping amount between 0.2 and 0.4 worked in this case.

The only thing left is to add a sphere. Set it to smooth shading. In the render section of the particle system choose object, and next to Dupli Object select sphere.

Then you are ready to go!

      Awesome tutorial and never knew about biods! That point where you had tublore changing priorities and it wouldn’t update, I’ve found with simultantions/cloth, you need to go back to the first frame of the animation, select your particle generator / object, hit tab to go into edit mode and then tab out again. Tabbing in and out seems to clear any temporary memory and update (important to be at the beginning of the animation too).Would LOOOOOOOOOOOVE to see a tutorial on how you can have a flock of birds animating flying cycles, take off and landing!

    Wow, that’s actually a really nice and useful effect! And not too hard to achieve. Thanks for sharing!
