[Julia K] “I have another quick question, how do you create a random effector to control the opacity?”
That’s a little trickier, but not too bad. What you’re going to do is create a separate random effector to control oppacity only. So, in the effector’s parameter tab, uncheck any P/S/R parameters and set the color mode to “user defined”. Set the color to white, and check the “Use Alpha/Strength” box.
Now you have to add a transparency channel to your cloner material and put the MoGraph>Color Shader in the transparency channel.
In order to animate the opacity you have to go back to the random effector and change the Effector>Random Mode to Noise or Turbulence. Then you can play with the speed and scale parameters to get the look you’re after.
