LayerComp is a layer-based compositing add-on for Blender, built to work in a way similar to After Effects. Rather than simply adding a filter over the screen, it lets you composite with AOVs layers, View Layer, media and more, organising the result as layers.
The add-on supports multiple compositing, adjustment layers and matte layers, with multiple mask control for each layer. It ships with more than ten feature nodes, and effect values can be controlled with a layer. You can copy and paste layers or effects between two compositors, and save, share, load and export custom effects and compositors as presets stored in .blend files. A dynamic search box and drag-and-drop for layers and effects sit alongside the interface, which is reachable from the sidebar in the 3D View, the Compositor and the Image Editor.
It was developed within an anime workflow that primarily used After Effects, so its approach mirrors that program. The developer describes it as a system and pipeline, noting it relies on users to build their own effect presets.
