Had a job that needed a HUD for the inside of a helmet (ala Iron Man). I started building the shapes I needed to make my own HUD elements to be animated. Then I remembered seeing some Pro Emitters that had HUD particles in them. I went to the Wondertouch site and there it was. I got lucky and there is a sale for Emitters 7, 8 and 9 for $90 so I purchased that. I used about 12 of the different emitters from all three libraries (mostly 7) to construct 12 HUD layers that I brought into Fusion to composite and complete that part of the job. I would estimate the Pro Emitters saved me about 5 hours of work which equals more money in my pocket.
