@Blissy First off make sure your putting them in the 'Particles' folder not the objects folder. Second, you must load each of them as I did not make Object Files for them. Open your 'Object Maker' and go to the 'Effects' tab at the bottom. Then you go to the 'Particles' tab and that is where you will enter the name of each of the particles, loading them and saving them individually into your own object category.
@Khizzer Glad you like them! More coming soon!
