Using AE CS5, I have a video containing moving features that needs tapered lines growing on and following along.
* I make a mask spline on a solid layer.
* I animate a null to follow feature and link the solid to this.
* I add trapcode 3D stroke to the solid layer to get the stroke effect on the mask line.
The problem is I can’t seem to get the stroke to line up and move with the mask line. I did manage to line it up by using front view mode in the camera options (of tracode 3D stroke) but then it wouldn’t move with the null motion.
You really don't want to change the scale(or really do any transformations) of the layer with 3d stroke. You want to do those transformations.
Without knowing the exact specifics of your track, I can't tell you how to do this step by step, but what you need to do is to link that tracking data to the the different properties under the transform pull
down within stroke. If it's easy, it might be as simple as enabling expressions and pick-whipping to the null's tracking data.
