I noticed that it seems that many people are having problems with the macros, and getting the red MISSING MACRO when rendering. I was having this problem too but recently solved it. The macros usually come with three files a .nri, .h, and UI.h
.nri file goes in user/nreal/icons
.h file goes in user/nreal/include/startup
UI.h file goes in user/nreal/include/startup/ui
My problem was I had my UI.h and .h files both in the ui folder. Only the UI.h files go in the ui folder.
Hope this helps.
