About this tutorial

Build a realistic door interaction system in Unreal Engine 5 using Motion Warping, Control Rig hand IK, root-motion animations, and animation curves. The character approaches the door, grips the knob, and opens or closes it naturally from either side.

The system supports four interactions—open inward, close inward, open outward, and close outward—and automatically selects the correct animation based on the character’s side and the door state. Control Rig and animation curves keep the hand, knob, and door synchronized throughout the interaction.

In this UE5 tutorial, you’ll learn how to:

Detect character’s side of the door
Store side-specific montages, warp points, and hand targets
Automatically select the correct opening or closing animation
Synchronize the hand, knob, and door using animation curves
Position the character accurately using Motion Warping
Align the hand with the knob using Control Rig IK
