Issues with Gaussian Splatting integration in Meta Spatial SDK (v0.9.2) – Standalone Quest 3
Hi everyone, I am an architect and urban planner, developing VR/MR projects in my spare time. I’m currently working on a native Quest 3 application to view Gaussian Splats for highly detailed virtual project tours. My Goal: Render native Gaussian Splatting (3DGS) on Quest 3 (Standalone). Synchronize the splat position with the real world for a seamless transition from Mixed Reality (MR) to Virtual Reality (VR) with a skybox. Targeting a minimum of 150k splats with stable performance. Previous Attempts: I initially used Unity with the Aras/Ninja implementations. While it works perfectly via Oculus Link (PCVR), it’s not viable for my needs because: PC Builds don't support the specific MR features I need for this project. The Android build (standalone) performance is extremely poor, even with optimized settings and a small 50k splat PLY file (unusable frame rates). Current Issue with Meta Spatial SDK: I’ve switched to the Meta Spatial SDK (Packages v0.9.2) to leverage the new native splat support mentioned here: Spatial SDK Splats Documentation. Despite following the documentation step-by-step: The splats do not appear in the scene. I am getting several reference errors (MissingReference/NullReference) that I can't seem to resolve. My Question: Has anyone successfully created a native Quest 3 APK using the Spatial SDK to run Gaussian Splats (~150k splats)? If so, could you share the correct workflow or point out common pitfalls with this specific SDK version? Any help or documentation beyond the official guide would be greatly appreciated!Is there any way to completely remove the boundary and make the play area unlimited size?
Say I have a very large area. Think of an empty warehouse bigger than a couple football fields put together. I want to create an AR application where my users can walk the entire area. The problem I'm running into is when I start walking I eventually hit the wall of the boundary and the AR application turns off, similar to what happens then you walk through the boundary while in VR. I get why this exists for VR but my users are in AR passthrough, so they can see their surroundings and are not going to run into anything. I need some way to allow my users to continue walking beyond the boundary without turning the AR application off. When I go into developer mode and disable the boundaries, A) that is only for development purposes (so I assume this means it won't work for a packaged application, and B) it turns off passthrough so AR is not an option. When I try to manually create the boundary using the "suggested boundary", I will start walking in a direction and the boundary behind me follows me, keeping the total size of the play area about 30'x30'. When I try to manually create the boundary using the spray paint lines, I hit an invisible "wall" while spray painting the boundary, and if I follow along the outer edge of this invisible wall with the spray paint, the area turns out to be a 30'x30' area. Is there a way to accomplish what I want to do? Is it possible create an AR application that allows users to walk around an area the size of 1-2 football fields? Thanks.

Unity colocation build with MRUK, getting this error in Logcat and "host can't share the room with group xx-xx.." on immersive debugger...

I am trying to create an app with qr code tracking, at first it went perfectly well, just for the first time only, object was spawned at qr code object where I wanted. But the second, third and next time and on and on. Whenever I scan qr code, the object keep be spawned at different places. I keep changing places where I start my app, at first I thought that was the reason for this problem, but even if I go back to the same place that it was spawned at the right place, this time the object was spawned where I didn't want instead. I have enabled Anchor Support Scene Support Experimental features Permission Requests On Startup >> Scene QR Code tracking , which are required for QR code tracking function. So I really don't know why this keep happening. I have tried "save my perference" and "not save my perference" for spatial data request when the app is starting. And the results are the same. I have no more idea to try. Please help me, Thank you.
Getting Analog Values from Joysticks in Spatial SDK Native Android App
Hi, I am trying to create an app that can track the joystick push values as continuous values rather than discrete pushed/not pushed. I am using the Spatial SDK and it seems to only expose getters such as ButtonThumbLL which return an Int representing whether they were pressed or not. I saw a similar post about 4 months ago that was left unanswered: Interface of getting Controller joystick travel range | Meta Community Forums - 1336257. I am curious if anyone knows and idiomatic way of getting the continuous values of how far the joysticks are pushed. Thank you.QR tracking, Remove spawned object.
I want to remove or delete the spawned object after oculus detected qr code. So I added a button for close and add listener to that said button, the function works as below image. Which it is closed for about 1 second or less, and the object keep showing up automatically even I look away from the qr code. Does anyone have any suggestions what I should do? Thank you.
