transitions folder

I have several transition packs from third parties such as ryan nangle and pixel films studios. some of my older transitions from ryan nangle are still in my fcpx, but when i try to get their actual file in my motion templates-transitions folder, they don't show up. im not sure how they appear in fcpx if they arent with the rest of my third party transitions?? anyone know where i can find the original folders with the ryan nangle transitions?

Some plugins are not built entirely inside of Motion, they are coded, and thus you have no access to them. Unless you're a good programmer and know how to deal with that coding.
