Dominique Posted March 16, 2022 Share Posted March 16, 2022 Hi everyone ! I am asking again how I would be able to setup a VR experience where I would have 2-3 VR Systems in the same space. For a more complete understanding, this is a description of the wanted setup in Unreal Engine : One Computer (without HMD) that only tracks Vive Tracker 3.0 to represent and manage complex simulations of a 3D object, such as a turret One Computer (with HMD) where the player should be able to interact / manipulate the 3D object One Computer (with HMD) where the player should be able to oversee the other player and be able to lightly interact with the 3D object Right now I am trying to make work only 1. and 2. together by syncing manually the world position of the vive trackers over network but it doesn't work as expected. When I tried to copy and past the config files (chaperone and lighthousedb), the vr player did not have correct distance with the 3d model. I'm not sure if I did everythin right, I have some experience in 3d graphics but 3d engine and gameplay is very recent stuff for me. I also read something about LBE but I didn't understand what it is ? Thanks in advance ! Here are some links i have already found and didn't help : https://forum.vive.com/topic/6443-vive-cosmos-multiplayer-in-same-room/ > SteamVR has implemented a bunch of error correction methodologies within the last year which actually makes a chaperone file dynamic - SteamVR now makes adjustments to the file at run-time without the user being aware of the changes which makes co-presence VR rather tricky (we have a tool for arcades that attempts to restrict these changes). https://forum.vive.com/topic/2828-4-players-in-same-play-area/ Link to comment Share on other sites More sharing options...

It feels like solutions for this exist to correct auto-calibration of mutltiple devices, but can't find any in-depth solution. Rorayn. Link to comment Share on other sites More sharing options...
HackPerception Posted May 4, 2022 Share Posted May 4, 2022 Most of Vive Focus 3's previously announced advanced LBE/enterprise settings are currently available - but VIVE is offering them as site/customer specific customization services. They're asking you to contact your enterprise sales contact, or to reach out via https://business.vive.com/ The most recent feature to ship was support for arUco marker-based calibration. @Rorayn@Hlander Link to comment Share on other sites More sharing options...
HackPerception Posted May 4, 2022 Share Posted May 4, 2022 @Dominique - SteamVR still doesn't have a great solution for co-location or driving multiple devices off a shared set of basestations. If you are building your own app - you can create your own calibration process to try to circumnavigate the lack of a good tracking co-location solution on SteamVR. You'd create a calibration process within your app where you have one or several "control points" within your environment that you calibrate your tracked object (controller/prop/headset) to which can align multiple . You can represent the locations of the control points in your environment with a physical marker such as a sticker or environmental art. If you're licensing an app, your limited to what the application supports but can use things like OpenVR advanced settings to try and dial the playspace in within the headset.
