• PathBlurFX brings a new dimension to After Effects by enabling blur, smear, and motion-style effects along a mask path, not just in linear directions. Rather than relying on generic motion blur, this plugin lets you generate a vector field from a path you draw, giving you precise control over how blur flows and fades across your element.

What It Does

• You start by creating a mask path in After Effects. PathBlurFX translates that path into a directional field, and then blurs (or smears) your layer according to that flow.

• You can control falloff along the path—from where blur begins to how strong it becomes, and taper it off toward the end.

• The plugin supports dynamic sampling, which keeps the blur effect smooth and consistent—even when your mask path has complex curves or varying lengths.

• Sharp direction changes can be softened by smoothing parameters, so the distortion doesn’t look harsh or unnatural.
