LongShadow is a full-featured, GPU-accelerated shadow plug-in for After Effects, developed by BGRA Entertainment. It creates shadows with control over every shadow aspect and includes shadow anti-aliasing.
Beyond that, LongShadow offers shadow texturing that controls colors and transparency with an external layer in 1D or 2D texture modes. A Brute-Force Directional shadow mode preserves the original layer's semi-transparency and anti-aliasing, and a Soft Shadow feature plus a post-smoothing algorithm shape the result. The package also includes a dedicated SoftShadow plugin with simplified controls for a simple solid-color shadow with a soft shadow look.
LongShadow runs across a wide range of After Effects versions, from CS6 through 2024, and a 2022 update added native M1 support. Free After Effects projects are available to download, and a demo video is also available.
