Generates procedural 2D-style smear frames and motion trails for 3D animated objects. This Geometry Nodes setup automatically creates stylized motion blur effects by calculating deformation arcs based on the previous frames of an animation. It functions on both individual objects and entire collections.

The system includes multiple operation modes: standard smears using a two-frame calculation, simulated extra-long smears for slower objects, multiple trailing objects, and a combined smear-and-trail mode. It exports custom shader attributes like 'smear', 'mask', and 'factor' directly to the Shader Editor, allowing for precise material adjustments across motion trails. The setup requires meshes with consistent point counts and must be baked prior to rendering.
