SpringArm3D¶

Category: Executor Tier: Plus

Purpose¶

The SpringArm3D Executor provides a native interface to control a SpringArm3D node’s collision behavior and length.

As added to your scene

Inputs

Activate (Boolean): When true, the executor updates properties and handles movement smoothing.
Target Length (Float): A dynamic input to drive spring_length via variable binding.

Outputs None

Properties

Core Configuration

Spring Length (Float, 2.0): The maximum distance the arm extends if no collision is hit.
Margin (Float, 0.01): The offset from the collision point to prevent the camera from clipping inside geometry.
Collision Mask (Integer Bitmask): Defines which physics layers the arm should collide with.

Smoothing And Catch-Up Logic

Enable Smoothing (Boolean, false): When true, the arm follows its tree parent using the authored local transform as the target.
Smoothing Mode (Option: Location, Rotation, Both; default Location): Chooses which channels interpolate while detached. Channels not selected by the mode snap directly to the authored follow target each tick.
Rotation Follow Mode (Option: Absolute, Additive; default Absolute): When rotation smoothing is active, Absolute lets the executor fully own the arm’s rotation, while Additive preserves extra local camera-look rotation applied to the same SpringArm3D and composes it on top of the parent-follow pose.
Smoothing Speed (Float, 5.0): How quickly the arm catches up to the parent.
Auto Top-Level (Boolean, true): If enabled, the executor automatically enables Top Level at runtime so the arm can move independently.
