This tool is useful to deform geometry. However, it can also be used to deform the path of particle systems and create funneling effects.

1. Click the Lattice tool on the Deform tab.

2. Select the points to deform and press Enter to confirm your selection.

3. Press Enter again to create a cage from the object’s bounding box or hold Alt to select a deforming point cloud from another object and press Enter to confirm your selection.

4. Click the transform node in the network editor.

5. Move the points of the cage in the scene view to deform the shape underneath.
