[OnApplicationPause not called when taking off the headset]

Hi @Fangh,

We recommend you to use below Unity script API as more formal way on Focus 3.

https://docs.unity3d.com/ScriptReference/XR.CommonUsages-userPresence.html

As "OnApplicationPause" or "OnApplicationFocus", these may vary depends on the design behavior and not 100% equal to user taking off / putting back the headset.

Thanks.

[Random crashing on UE 4.26.2 with WaveVR 4.3.0 on Focus 3]

Hi @RoosterPrincess,

After internal testing and verification, we narrowed down the crash happened every time at the line “InLayerDesc.HasShape<FCylinderLayer>()”, which is a struct method provided by Unreal Engine. Though we don't confirm the root cause from the UE engine, we try to have workaround for function access and under verification. Should provide the hot-fix UE plugin on the website soon.

Thanks.

[Detect Focus 3 vs Focus Plus in Unity Wave SDK]

Sample code by using Essence API:

 using Wave.Essence;

            var controller_r = WXRDevice.GetRoleDevice(XR_Device.Right);

           if (controller_r.TryGetFeatureValue(CommonUsages.isTracked, out bool value))

                     string rightControllerInfo = controller_r.name + " is tracked.";

 If you used the InputDevices.GetDevices, you have to check the characteristic of left/right/head devices.

 

 Sample code by using UnityEngine.XR:

                 /// <summary> Wave Head Mounted Device Characteristics </summary>

                     const InputDeviceCharacteristics kHMDCharacteristics = (

                                InputDeviceCharacteristics.HeadMounted |

                                InputDeviceCharacteristics.Camera |

                                InputDeviceCharacteristics.TrackedDevice

                     );

                     /// <summary> Wave Left Controller Characteristics </summary>

                     const InputDeviceCharacteristics kControllerLeftCharacteristics = (

                                InputDeviceCharacteristics.Left |

                                InputDeviceCharacteristics.TrackedDevice |

                                InputDeviceCharacteristics.Controller |

                                InputDeviceCharacteristics.HeldInHand

                     );

                     /// <summary> Wave Right Controller Characteristics </summary>

                     const InputDeviceCharacteristics kControllerRightCharacteristics = (

                                InputDeviceCharacteristics.Right |

                                InputDeviceCharacteristics.TrackedDevice |

                                InputDeviceCharacteristics.Controller |

                                InputDeviceCharacteristics.HeldInHand

 

                      var inputDevices = new List<UnityEngine.XR.InputDevice>();

                     InputDevices.GetDevices(inputDevices);

 

                      foreach (UnityEngine.XR.InputDevice id in inputDevices)

                                bool isRight = id.characteristics.Equals(kControllerRightCharacteristics);

[Haptics API in latest wave unity sdk 4.1.1?]

Hi,

In Wave Essence:

You can use Wave.Essence;

You can use UnityEngine.XR;

<InputDevice>.SendHapticImpulse(0, amplitude, duration);

Thanks.

[Our App exited abnormally]

Hello, @JennyKIM,

It seems that the crash originates from Unity native libraries.

Another finding is that, right before the crash stack, there is this line:

09-01 18:50:46.834 24050 24080 W VRWatchDog: SUBMIT-TIMEOUT WARNING: 1161 ms

 

Which might suggest the application was frozen before it crashed.

However, as suggested at the beginning, the crash stack originates from Unity native libraries which means that it is pretty much impossible for us to find the root cause of this crash.

[Vive Business Streaming SteamVR drivers no skeletal movement?]

I think you are mentioning analog grip button.

Currently, VBS BETA supports SteamVR skeleton as Cosmos. It supports analog trigger button, but not for grip button.

Understand what you mean for finger movement animation based on the analog finger data.

May we know if you also use this analog finger data for actions in game?

[Vive Business Streaming SteamVR drivers no skeletal movement?]

Hi @ShadowBrain,

 

Controller skeleton data is supported in VBS 1.04.

You could switch to VBS BETA to try it via Console -> Settings -> Advanced -> Beta program.

Thanks.

[Direct Preview with Focus 3 in UE]

There are two suggestions

1.      For Direct Preview, please make sure wvr_plugins_directpreview.dll has loaded successfully.

1). Try to move the project to somewhere that the path did not include black. (For instance, “Unreal Plugin” include a blank).

2). Open the Unreal editor, then check the log to see if wvr_plugins_directpreview.dll found.

The log will show “WVRDllLoader: Load wvr_plugins_directpreview.dll success.” in log if load successfully.

The following is the failed case.

LogWindows: Failed to load '../../../../../../Users/Heath/Documents/Unreal Projects/SDK400/Plugins/WaveVR/Source/WVR/lib/Win64/wvr_plugins_directpreview.dll' (GetLastError=126) LogWindows: File '../../../../../../Users/Heath/Documents/Unreal Projects/SDK400/Plugins/WaveVR/Source/WVR/lib/Win64/wvr_plugins_directpreview.dll' does not exist WVRDllLoader: Failed to load wvr_plugins_directpreview.dll

 

2.      Please replace the NDK version r23 with r21.

And here comes the Android settings for reference.

Hi @jwatson,

May we clarify if you use USB or WIFI for Direct Preview? 

If it's under USB, then it's non issue.

In addition, may we know if your environment is Unity 2020 and do you enable URP?

Thanks.

[Eye tracking data has hard max in all subjects]

Hi @DrewPruett,

You mentioned that we do not calibrate the eye tracker, is that meaning you don't run our calibration app before your use case?

In our requirement, the calibration app needs to be run before use or change to different people to minimize the deviation.

Could you check that first?

Thanks.

[Unity, trying to get the Player defined Room setup.]

Hi @Knase,

4x4 is the default range of play arena if you never complete VRS RoomSetup, so we recommend you to finish the process then access the API.

Furthermore, call WVR_GetArena will only return the inner maximum rectangle by user defined play area.

Please be noted to use the latest SDK 4.1.0 with the ROM version (after 114) to have this function enable.

Thanks.
