Hi, im an intro/logo designer/animator, and im interested in your 3d object animation project.
So i read ur description and i can show u something similar that ive done before (without the Saber plugin, but i have that one aswell).
You can see it here along the edges of the 3d letters: [login to view URL]
Here you can see some of my past work (includes that example), just to get an idea of my proficiency with After Effects: [login to view URL]
And if you wanna see more let me know.
I tried opening your project, but it seems the project is saved in an incompatible version (i have version 12 (CC)). But i checked the model you included inside, and it really depends which paths you need animated, since Saber (or any other stroke effect is 2d, with the ability to be positioned in 3d).
Let me know.
