Effect Matte, from Plugin Everything, applies a matte directly to a layer in After Effects. It adds a sized, customizable matte that removes the need for a separate layer set up as a track matte. When applied to a layer, the matte auto-sets, and an invert matte option is included.
Shaping the matte is handled through a few controls: expansion in both positive and negative directions, roundness, and feathering. A couple of conditions apply. Effect Matte requires layers to have continuous rasterization enabled, its Auto Set Matte feature is not compatible with shape layers, and it works with parented layers only on CC 2018.
The plugin runs across a broad span of After Effects versions, from CS6 through 2026. Version 1.4.0 (March 2025) addressed multi-frame rendering stability, and earlier updates brought native Apple Silicon support and multi-frame rendering. A demo video is available.
