to make things super simple and easy I will create an imaginary scene so that you guys can get a good understanding of what am trying to archive.
1: new comp
2: 1 solid added
3: add element 3d and put an airplane to the scene.
4: back to the main AE, solid, effects of element 3d
5: utilities / generate 3d position and added point to airplane turbines.
6: new solid / particular illusion.
now how do i attach P,I to the 3d null am stuck
