# Known Issues for Unity

There are currently a couple of known issues that may affect the development workflow. These are known issues and will be tackled in future releases of the Unity package or the Snapdragon Spaces Services runtime.

If an issue is not present, check the overall SDK Known Issues

# Plane Detection issues

Plane detection is not reporting any tracked planes currently if AR Plane Manager is used in combination with both AR Tracked Image Manager and the AR Anchor Manager. Combining AR Plane Manager with AR Tracked Image Manager OR AR Anchor Manager is working correctly.

# Rendering issues

# Frame tearing

Under fast movement, the rendered image might introduce tearing artifacts.

# Gradle build issue

In some instances, adding a custom controller archive might lead to Gradle caching errors. In that case, removing the temporary Gradle project folder generated in the project folder under Temp > gradleOut might resolve the issue.

# Hand Tracking issues

# General

  • Head movement may induce hand movement.
  • Camera access has to be manually granted for the Spaces Services application.

# UX limitations

  • Releasing object can only be performed with the Open Hand gesture.
  • In some conditions, occlusion between hands may result in hand inversion between left and right.
  • If the hand avatar is displayed, some jitter may be perceived on the finger tips. As we are in AR, we recommend not to display the hand avatar to maximize the user experience.
