Don't held your breath.
AE is a BITMAP application that's able to ACCOMMODATE vector graphics. AE rasterizes them, i.e. it turn them into BITMAPS. It does not deal with vectors directly.
You want Illustrator layer styles?? Make your illustrator images larger than you need to. Import them into Photoshop. Flatten them. Import them into AE.
Or find a different workflow. You're tilting at windmills.
I wish it were that simple and in a perfect world, I'd change my workflow but the majority of files I handle is Illustrator files.
You see, when you use "Create Shapes from Vector Layer", AE creates a new shape layer that is also vector but fills the mask/shape with only a solid fill instead of multiple fills/gradient. In theory, if this mechanism exists, I can't see why multiple fills/gradients from Illustrator can be ported to AE in a similar method.
Flattening my layer styles from one object in Illustrator isn't an ideal solution especially if you're dealing with many different fills/layers in one object. I ended up recreating each fill using gradient fills in AE which is a similar mechanism that exists in Illustrator... but obviously this process is time consuming.
I can elaborate if needed but figured I'd post to see if I might be missing a solution somewhere.
To go further, I finally found that this mechanism doesn't exist as seen here: Create and customize shapes and masks in After Effects
Hopefully Adobe gets to fix this at some point...
The following issues are known:
- Not all features of Illustrator files are currently preserved. Examples include: opacity, images, and gradients.
- Converted shapes ignore PAR overrides specified in the Interpret Footage dialog box.
- Gradients and unsupported types may show as 50% gray shapes.
- Files with thousands of paths may import very slowly without feedback.
- The menu command works on a single selected layer at a time.
- If you import an Illustrator file as a composition (i.e., several layers), you cannot convert all of those layers in one pass. However, you can import the file as footage, and then use the command to convert the single footage layer to shapes.
