FPS not getting more then 30
How can we increase fps of oculus quest. We are using xr interaction toolkit. In empty scene with just camera i am getting 55fps max. But in any project i am getting just 30fps. I have also done normal urp setting you can go though in photos attached. I also applied occlusion culling.
How to geometrically align a 3D model to real furniture?
For my video-see-through AR application I want a model to automatically be placed on the biggest found table surface. I achieved the first step: The model is correctly positioned at the table center. However, the orientationis not correct. I want the model to "lie down" on the table, means laying on the back, facing up, while the longest side of the model is orientated just as the longest side of the table - see the following pictures: After a very long time trying, I could not figure out how to align the model correctly. If you have any idea/hint/ or clue I could try, please let me know. Used Asset for testing: Low Poly Human I added an Empty (called ModelPlacer) where I added the script (see below) and pulled this asset in the modelInstance field.

Hello everyone, my problem is that the room mesh doesn't update. I want the room mesh to be updated, everytime my application is started again. However, it seems like the mesh loaded from the first time is always reused and doesn't update, even when I update the application. How I update: I build an AR app (.apk file) on my laptop with Unity and deploy it to my Meta Quest 3 headset, which overrites the previous .apk file. What I see: a flickering mesh all over the place of the "original room", even when I go to a neighbouring room, it shows the mesh of the first room (it's like looking through a wall). I followed the set up instructions and my "Hello World" and first tries worked properly. For my current version I am Using the following building blocks: Camera Rig Passthrough Scene Mesh MR Utility Kit Scene Debugger As you can guess I am quite new to Meta Horizon Development. I've been stuck on this problem for quite a while now. Any tips/advice/recources to resolve this are highly appreciated.
Using the Quest 3 passthrough for Augmented Reality on architectural project
Hi, we’re on the verge of buying a Quest 3 for a specific solution to a VR/AR need. We’ve designed and completed a physical two-storey hotel suite, but the spiral staircase connecting the two floors has been delayed. We have a fully modelled and textured 3d model of the staircase and was hoping to use the passthrough element of the Quest 3 to drop the staircase in position in the existing hotel room and allow potential customers the opportunity to see it while wearing the new Quest. Problem is there’s little to no support on where to even begin with this so can anyone advise on where to begin? Is it possible? Many thanksCamera motion in passthrough
Hi! I am working on developing an app that rotates or translates the field of view during passthrough at different rates. I was wondering if there was a way to have the cameras on the Meta Quest 2, 3, or Pro track a virtual object that moves back and forth? I want the cameras to move back and forth independent from the user's head motion. I can clip some peripheral vision to make this possible as well. Does anybody have a recommendation on how to do this or think it is even possible with the current plugins? Thanks!How to develop an AR App for meta quest for Object recognition
Hello I am developing an AR app for meta quest pro and meta quest 3. I have already an app for it which works on Android Smartphone phone but the experience not so good. In that app i am using tensorflow on Android and recognizing the object at runtime and over laying some icons based on the recognized the app. I want to (1) Is there anything similar for Meta Quest? Like object recognition and icons over laying (2) Do i have to develop in Android only? (3) Any Unity framework to do so? Looking for soem good developer adv Regard.Any future for mixed reality applications on Quest Pro that track real-world objects?
After purchasing a Quest Pro, because I wanted to explore mixed reality applications that track real-world objects, I found out that it is not possible yet because they don't let applications use camera data due to 'privacy concerns'. You can't even track AR tags. Since this is a mixed reality headset it seems this would be an essential functionality and priority for them. People use camera data all the times all the time on phones to create mixed and augmented reality applications. Is this something we will see them eventually release an SDK for (like AR Foundation) or should I just return it? Attaching a separate webcam on my headset is not an option.
