An Onion Skin preset controlled by a handy pseudo effect.
NOTE: This effects rig only works when applied to shape layers, continuously rasterized vector layers, or collapse transformed precomps. Footage items (solids, photos, videos, etc.) MUST be precomposed and have the collapse transformations switch enabled prior to applying the preset.
Install the .ffx file in your local After Effects or User Presets folder, refresh the presets list in After Effects, and have fun!
Compatible with After Effects 2021 v18.4.6 and newer.
