> Mike Cook Portfolio » Maya MEL – Emit Particles from Object Velocity

Particle dynamics can be tricky to setup. This script makes emitting particles from the cracks of objects much easier.


  • Automatically generates expression connected to group node to handle particle emission.
  • Group node contains all the attributes to handle particle emission. (no need to dive into the expressions)
  • Any objects or groups of objects can be parented under the group to tell the expression which objects should have particles emitted from them.
  • Automatically creates a particle and adds it to the group. Additionally it will create per particle attributes for random scale, and rotation and create the necessary particle expression to handle this. (you can tweak these values after creation). All you need to do is create a particle instancer of the objects you want to be instanced and set the instancer to the pre-made particle attributes.
