OVR UI Helpers - Raycast LaserPointer and cursor not displayed in Quest build from Unity 2019.3.0f1
Hi all, really hoping someone might have experienced this same problem and found a fix, as it's really frustrating to not understand WHY this is happening. I'm Using Oculus Link and Unity to iteratively develop and test (using the play button in unity, which automatically plays on the USB connected Quest). I'm following the guidance for using UI helpers on a canvas object and have had no problems with being able to interact with all aspects of my UI using the touchcontrollers and the included raycast and linerender "Laser Pointer" script. The problem i'm having is when i come to do a build. Everything builds fine, with no errors but when I play it on the quest, the laser pointer/ line renderer not only doesnt show up it doesnt give me any interation with the UI when running on the Quest. Even stranger is the fact that when I plug my Quest back into the PC and start developing again in Unity, the problem then appears there. None of the UI interaction is working and the line renderer doesnt show up !? The only way to get the functionality back is to exit Unity and reload the scene. Everything then goes back to normal.... until I do a build again!? This may well be a Unity issue, I'll be asking kindly on their forums too, but would appreacite any advice or if anyone else has experienced these kinds of UI interaction problems with a Quest Build? Thanks in Advnace Andi
Stereo Layer Transparency broken for UI Widgets on Quest
To improve the quality of our in game UI, we recently moved it from world space widgets to Stereo Layers. However, transparent Stereo Layer have black backgrounds on the quest where it is supposed to be transparent. After setting up the stereo layer, so that it gets live textures from the Unreal UMG system, the transparent parts appear black on the Quest. So here how it looks on the Quest: And how it looks on the PC with oculus link and VR preview in engine (this is how it is suppose to look): The issue only pops up with Live textures, if I place a sprite with alpha channel as the texture, it is displayed correctly with alpha blending. One thing we have already tried is creating the render target in C++ and ensuring that the clear color has the alpha of 0, so (0,0,0,0) and the format supports RGBA. We are on Unreal version 4.25.3 on the Oculus Unreal Branch built from source. Any tricks to get this working? Thanks for the help! DanielAdding ray pointer from Oculus Hands to interact with UI
I am trying to add a ray pointer from Oculus Hands to interact with UI. I managed to get the ray as shown in the screen capture below. However, as you can see, the laser pointer starts from the wrist position and aligned towards the right instead of pointing straight. Appreciate your suggestion if you know how can I correct this to point forward? Also, this laser pointer appears only on the right hand. Is there a way to change this? Please see my settings in Unity below.
How to use graphics raycaster with physics raycaster?
I'd like to be able to interact with UI elements and 3D objects together in the same scene. I have the OVRRaycaster on my canvas, and OVRPhysicsRaycaster on the OVRCameraRig. Both work correctly by themselves, but the Physics Raycaster will still hit an object even if there is a canvas in front of it. I've played around with the blocking objects, blocking masks, and other settings. I've tried EventSystem.current.IsPointerOverGameObject() but it didn't seem to do anything. And I've tried to tweak the OVRPhysicsRaycaster script to no avail. From what I've read, the Physics Raycaster doesn't detect any graphic elements, so potentially Graphic Raycasts should be done first, and if nothing is hit, then call Physics Raycaster? Does the Oculus SDK have a solution for this or am I better off writing my own system?
Oculus Quest 3 Dot Loading in Unity App
Unity 2019.1.3f1 and most recent Oculus SDK I built out a quick UI where the user is required to interact with this keypad. They need to click on the buttons to enter the code and press enter. Except every time a button is clicked, three dots appear and the headset takes has to load. Not sure why as this has worked on every other headset with no issues. Would love some feedback!
