# Existent v0.0.2 Release Notes

### Change Log: <a href="#change-log" id="change-log"></a>

### New Features

* **Variable Speed for Vehicles:** Vehicles can now drive at a speed defined by a developer-provided FloatCurve. By setting `bConstantSpeed` to false, speed can vary freely, including going negative, while still smoothly aligning with source and destination Spaces. This includes:
  * Automatic adjustment of driving time to match the journey distance based on the area under the custom curve.
  * A separate `SpeedScale` parameter to adjust the maximum speed and driving time.
  * Automatic normalization of the curve to a time domain of \[0, 1].
* **Custom Curve for Vehicle Scale:** Added an option to vary vehicle scale using custom curves.
* **New Grip Edit Mode:** Introduced a new grip edit mode in the blueprint editor with a fully customized details panel for the grip component. This allows:
  * Editing a specific pose or creating a new pose and entering edit mode.
  * Using the details panel as a tools panel in edit mode.
  * Manipulating animation sequence hand bones and saving changes back into the animation sequence.
* **RealityBridge Enhancements:**
  * Alignment Accuracy Display: Introduced a feature to display alignment accuracy in RealityBridge.
  * Net Mode Information: Send net mode information to RealityBridge.
* **Documentation**: You can now find the Blueprint Nodes API [index](https://docs.existent.com/documentation/resources/existent-api/index "mention") on our documentation

### Bug fixes & Improvements

* **Scaled Spaces**:&#x20;
  * Fixed the player-out-of-bounds check for scaled spaces.
* **Full Body Scale Fixes**:
  * Updated parent scale calculations and draw debugs.
  * Fixed dynamic target distances, spine calculations, and arm/leg scaling issues.
  * Resolved leg solver cached foot direction and dynamic target generation.
  * Improved root orientation generation and fixed spine twisting.
* **Debug Renders**: Added debug renders (in editor and backstage mode) for varying-speed Vehicles to visualize speed and acceleration values at regular intervals along the journey.
