Node Stacking in Fusion is a mix between multi-pass compositing for 3D animation and precomposition in After Effects. Unlike traditional multipass compositing, it can be applied to 2D text and graphics. Tony Gallardo demonstrates how to use Node Stacking for motion graphics.
With Node Stacking, you can make multiple instances of the same text and apply different effects. These might include glows, strokes, color corrections, and displacements. You can then composite them atop each other. Node Stacking allows for far more control over every aspect of the composition than possible otherwise.
