Failed to load display system / Unable to start Wave XR SDK Plugin

[JHibbins]

See Attachment in Unity 2020.3.34f1

I was working then has stopped, has anyone come across this before?

I have re-installed unity, rolled back my git and no change

Hi @JHibbins,

Could you try with a new Unity project and import Wave XR SDK?

Please double check your project is using Android platform, thanks!

[JHibbins]

I fixed this by using the latest wave version, I was using a beta package

[JHibbins]

I resolved this, it's because we were changing Quality Settings, the action of changing quality settings in unity meant the screen goes black, we now just commit to quality from defaults

Hi @JHibbins,

Do you mean the Quality Settings was changed from Medium to Very Low?

[JHibbins]

Explicitly calling this function results in a black screen, so we just removed this function and setup the defaults based on platform

public void UpdateVideoSettings()
    {
        switch (Options.Option_Video_Shadows)
        {
            case Options.ShadowsEnum.DISABLED:
                QualitySettings.SetQualityLevel(5);
                break;
            case Options.ShadowsEnum.HARD_ONLY:
                QualitySettings.SetQualityLevel(6);
                break;
            case Options.ShadowsEnum.HARD_AND_SOFT:
            default:
                QualitySettings.SetQualityLevel(7);
                break;
        }
        // ANTI ALIASING
        switch (Options.Option_Video_Anti_Aliasing)
        {
            case Options.AntiAliasingEnum.DISABLED:
                QualitySettings.antiAliasing = 0;
                break;
            case Options.AntiAliasingEnum.MULTI_SAMPLING_X2:
                QualitySettings.antiAliasing = 2;
                break;
            case Options.AntiAliasingEnum.MULTI_SAMPLING_X4:
                QualitySettings.antiAliasing = 4;
                break;
            case Options.AntiAliasingEnum.MULTI_SAMPLING_X8:
            default:
                QualitySettings.antiAliasing = 8;
                break;
        }
        UnityEngine.XR.XRSettings.eyeTextureResolutionScale = Options.Option_Video_RenderScale;
        QualitySettings.lodBias = Options.GetOptionVideoLODBias();
    }
