Inputs occurring in a different position in the Playground preview page compared to in Unity#

This could be caused by the preview of the capture being a different resolution than the rendered video in Unity. The input position is therefore getting scaled incorrectly.

Possible solutions:

  • Adjust the resolution in Playground to match the resolution in Unity.
  • Record tap inputs closer to the centre of the screen if possible.

Playground Fields not showing up#

This could be occurring due to ISerializationCallbackReceiver not being implemented.

Possible solutions:

  • Implement ISerializationCallbackReceiver in your scripts where fields have been marked. (Example below)
using Luna.Replay.Playground;
public class PlaygroundExample : MonoBehaviour, ISerializationCallbackReceiver {
[LunaPlaygroundField("Color of the player", 0, "Player Controls")]
private Color playerColor =;

Can't build and upload to Playground; Luna.Network.Replay.Base+yz error#

Example of this error


This could have occurred due to invalid authentication.

Possible solutions:

  • Logout and log in again.
  • Verify you are using the same account in Playground that you are logged into from within Replay in Unity.
