We are working on a project using UE 5.4 (commercial release, Remote Rendering only) and ML2. We want to take cad models and Align them to their Large real world counter parts using UE blueprints. Due to sensitive data, we can not use anything cloud. Essentially user puts on headset look at real …

So some good news, I got it to read the Aruco code now, but it doesnt do anything after that. I have a print string in UE for the and just returns the cords as 0,0,0 when I move the Aruco around different positions. Also in the Examples project file under the stats window of the aruco it also rea…

Hm, sorry, that is odd. Yes, the debug coordinate system should follow the marker around if things are working correctly. The example level will render a coordinate system on top of the marker as well. I would guess that you see the coordinate system stuck at 0,0,0 in the example level as well righ…

Actually, one thing just for sanity~ I'm sure you've tried this, but you could try rebooting your pc (to quit Unreal and ensure that the remote render service is restarted for good measure). Then, open the project, and the very first time that you try using the VR preview in Unreal after opening the…

[image] aheaney: I just tried running the v1.6 example project with the commercial release of UE 5.4.4 from the Epic Games Launcher and it does work for me I sent the project over to my coworker, and he tried it with magic leap exact same results. Both in my proj and the example project, usi…

I just tried it again and it worked okey. I just sent you a copy of my test project. It should have kicked you an email, but I'll dm you a direct link since this thread is public. The windows folder has a the app packaged as an exe. It just renders a debug axis on top of Aruco markers with the defau…

Hi Adam, thanks for sharing your proj with us. I tried it both the packaged exe and the UE proj file both with same results. It will draw the debug cord only 0,0.0 when Aruco is recognized. It will not place the debug in space on top the aurco code. Its really weird this works for you guys, but …

Hello, np. Yep, I was using all of the same versions. Latest remote render service & viewer (v1.15.131). It's interesting that you and your coworker both had the same issue. If you reproduced the same behavior with the exe that I sent you, then that would eliminate any differences in your toolchain…

Hello, I sent you a native sample apk that you can try running on your devices to verify that the tracker is at least working correctly. Note that the sample is configured to detect 5x5 Aruco codes by default. The generator on chev.me is set for 4x4 by default. It might take a bit more effort to …

Hi Adam, Thanks for the apk file, I tested it and it works great. What do you suggest we debug next, UE, remote rendering? Also would you guys be able to do a webex? Might be faster than troubleshooting over email. Thanks Philippe

Hey Philippe, I know it's not ideal, but we've been trying to keep support to the forums for now. First thing would be to check the UE log for any error output there. If an OpenXR function call failed, then you would likely see some error output in the Output Log in the UE editor. Another thing th…
