Controllers not working - Entering MR portal fixes issue temporarily

[milos12345]

Overview

On Unity Play the Controllers are not active. Pressing Win key on controllers to open MR portal and clicking the app again makes the controllers visible. Every time the play mode is restared the same steps are required to enable controllers

Steps to reproduce

Happens with example scenes, and also with an empty scene with just MR toolkit activated and project/scene settings applied

Unity Editor Version

2017.2.1f1

Mixed Reality Toolkit Release Version

2017.2.1.0

I am experiencing the same problem

@NeerajW @keveleigh It seems like this is the regression in Unity 2017.2.1f1. Running the same project in MRTP5 does not show this symptom. Had the same issue in early MRTP version which has been fixed from MRTP4.

Has anyone opened a bug report with Unity yet?

Hi Stephen, I didn't open a bug report with Unity.

[StephenHodgson]

Please do so and give us a case number here.

With a little Debugging of the MotionControllerVissualizer.cs, I see that the UnityEngine.XR.WSA.Input.InteractionManager does not have any InteractionSourceStates available at the time the script is executed. Also when the action of clicking the Windows button to go to portal and then click on application to resume, the MotionControllerVisualizer does not execute the Awake override. But, the controller models become visible. Just wondering if Unity is loading the controllers themselves in this version?

I have downloaded and installed Unity 2017.3.0f3 this issue is not present in the Unity version.

[ivan2007]

I confirm that this issue is not present with Unity 2017.3.0f3.

Official answer from Unity (https://fogbugz.unity3d.com/default.asp?980399_b1hka3slivv4klvn):

Hello,

My name is Denisas and I have been investigating your case. The issue with the controllers is fixed in the latest version of Unity

I'm using Unity 2017.3.0f3 and having this problem. It does not appear to be fixed. The "workaround" of "Pressing Win key on controllers to open MR portal and clicking the app again makes the controllers visible" does not work.

I'm using an Acer MR kit as part of Microsoft MR dev program. Test scene is the MotionControllerTest from latest download of https://github.com/Microsoft/MixedRealityToolkit-Unity Headset and gaze tracking all works fine, just not detecting the controllers. They pop up fine when hitting the win key to drop into MR Portal, but disappear as soon as you go back to Unity.

I'm using Unity 2017.3.0f3 and the problem is not present. You don't see nothing or you see two blocks as controllers?

[sonicviz]

Nothing at all, but switching to MR Portal they show up just fine. The disappear going back to Unity.

Update: My bad, I had not switched the project to Universal Windows Platform. All OK now! ty,

I'm having the same problem with Unity 2017.2.1f1 and v2017.2.1.1 release. In the answer for the bug in unity reports it is closed and fixed in the latest version of unity. What version they refer to? What is the latest version of unity we should use with the toolkit?

[ivan2007]

@cybergoulion, I'm using Unity 2017.3.0f3 with the current release of MRTK. The problem is not present.

[cybergoulion]

@ivan2007 Thank you, I was testing it myself just now and I also confirm that it works as expected up to 2017.3.1f1. Generaly I am reluctant to try the latest versions of unity because in the past I had compatibility issues with the toolkit, but it seems we are way past that now :-)

Happening again on Unity-2017.4.12f1 with MRTK 2017.4.1.0
