Im having a hard time trying to get the intersections between 3D layers. Im trying to replicate a style (link to image attached). It is also seen that the intersection isn't only between the layers, it is also between the text and the plexus in the back. I tried using track mattes, but if there where multiple intersections for one line it would not appear.
In that image, you have lines that are on separate layers which are blended in difference mode. They are not actually intersecting on the same layer. The plexus effect is on top of this, not intersecting anything.
