do I need a plug-in?
Hi, This is quite a specialist question, but I feel like I’ve hit a wall..
I have some footage that I’m wanting to composite a layer into.. I’ve figured out the perspective of the camera footage and understand that to make the composite layer look accurate it will need to be using the same perspective, that bit makes sense. The footage is of rapid motion through a tunnel, the layer I’m wanting to composite is a small solid following a path, to create the effect of a marker writing graffiti I have added an ‘echo effect’ to the small solid to give it a ribbon-like appearance (the end product will look like a dynamic line, writing graffiti on the wall of the tunnel while the camera moves rapidly through it)
I can create the graffiti effect flat onscreen in 2D bit as soon as I want to change the angle so it fits within the same perspective as the footage it stops working, the solid still follows the path but won’t change perspective, it stays 2D, I understand that the effects are 2dimensional, but thus far this is the only way I can think of to create this effect.. I’ve tried precomposing the composite layer before changing its angle on the y axis, no good. Do I need some kind of plug in to achieve this effect? -

[flector] “the solid still follows the path but won’t change perspective, it stays 2D,”
the problem is that paths are 2D and stay 2D… Is your path a motion path? Did you change the layers orientation? Did you check the “3D”-Button for the layer? If yes and your path stays flat, try moving a camera instead of the layer. Keep the footage layer 2D so it

If I underestand your problem, try this. Create the solid, turn on its 3D switch. Create a motion path including movement along the z axis. You want the motion path to follow the angle of the tunnel. Right click the layer in the timeline and select auto orient: orient along path. Rotate the y axis 90 degrees. Precompose the layer and choose move all attributes to a new composition. In the new composition turn on colapse transformations, now add the echo effect and adjust its setting to what you want.
