Using Touch Input to Draw smoothing-aliased lines

Just to avoid reinventing the wheel and having to implement my own algorithm I wanted to know if there was an easy way to do this built in to Unreal.

I wish to use the touch input to draw a textured line, have it smooth out the input (anti-alias it) and add it to the physics world of a 2d game (ala crayon physics).

Is this something I would have to implement from scratch myself or are there some baked-in blueprint nodes that can help get me started.

Appreciate the help.
