Unreal Engine Tear Line Plugin

A spline based procedurally generated fluid (drop and trail) simulation system, suitable for both cinematics and runtime gameplay

Documentation

The ability to control both the path of the Tear Line, as well as the shape of it allows us to create a realistic drop of flowing fluid.

BP_Tearline

The heart of the system. Containing a procedural TearMesh component defined by two spline components:

TearShape: closed spline determines the outline shape of TearMesh

TearPath: spline points sets the path the procedural mesh will take to grow on

Along with a static mesh component: Teardrop

Calling StartTear will start the system. We can control tear duration, when the drop falls, how the trail fades, the fluid material and more.
