Smear Deformer

Creates a stretching of the object based on movement

It uses a simulation zone, maybe sometimes you need to delete the cache and after getting the desired result, be sure to bake the result.

Settings

Object/Geometry mode – selects how the deformer is driven. In Object mode it reacts to the movement of the object itself, while in Geometry mode it reacts to animation happening inside the geometry nodes.
Selection – Enabling or disabling simulations by selection type
Weight – Weight for each model or geometry.
Smear – How much the geometry stretches,.
Blur – Blurring on neighboring points helps to create softer transitions for stretching. It also slightly reduces the effect.
