Features

• Cable Cutting - cut at any point, with auto-destroy and regrow features

• Cable Physics - particle-based solver with world collision, rigid endpoints, drift, and wind

• Wrapping Cable - section-based simulation with dynamic wrap anchors around geometry

• Chain Mode - render cables as fixed-size chain links that feed in and out during extend/retract

• Mesh-Based Visuals - real deformable static-mesh geometry, swap in your own tube/chain/hose/cables

• Cable Break - real time breaking/snapping based on tension thresholds and physical force

• Multi-tier LOD - (Full / Medium / Low / Sleeping) with global budget caps

• Rope Climbing - input-driven climb with gravity sliding, friction, stamina

• Vehicle Towing - physics-coupled cable with stiffness, damping, break force, tension events

• Custom Gravity - custom gravity directions, runtime modifiable

• Spline Cable - additional cable type shaped by a spline component

• Grapple Swing - aim to attach, pendulum physics, pump-swing, launch on release

• Zipline - rideable cable, configurable and BP controlled

• Pulley - mechanical pulley components allowing cable to slide through with optional friction

• Trace Collision - cables respond to line traces, sphere/box/capsule sweeps, multi-traces

• Runtime Pinning - pin cables to the world or actors with socket support

• Tether Component - visible rope to any target with leash physics and slide along cable

• Length Leash - optional hard-clamp keeps endpoint actors inside the cable's max length

• Cable Interaction - proximity or aim detection, grab, drag, pin, unpin, cut, extend, retract

• Tendrils - spawn tendril clusters of cables crawling and wrapping on surfaces

• Cable Webs - auto connect cables between endpoint markers with cascading defaults

• Placement editor mode - Place/Wrap tools to draw cables directly in the level editor

• Niagara Integration - custom Data Interface exposing particle positions and cable length to VFX

• Rigid Endpoints - stiff particles at start/end for rigid connectors

• Pull - mass compensated force, auto-retract, arrival detection

Blueprint-First

• Built for Blueprint users, no C++ required!

• All classes, properties, functions, and event dispatchers are fully BP-exposed

Performance

• Multi-tier LOD (Full / Medium / Low / Sleeping) with global budget caps

• Parallel solver across CPU cores

• Sweep-based particle collision with adaptive trace priority

• Overlap capsules for spatial queries without per-frame traces

• Dozens to hundreds of cables possible with the right LOD settings!
