As you can see from the image on my right how the orb has changed and gained fairy like bubbles to give it a better feel. How we done this was by going into the brush tool box and creating a new brush set-up, put the size down and then went into scattering to set the control to fade with spacing of 30% and size of 12% both axes were on to make sure that not only one side has this effect it also has a mininum diameter of 25%
