    Hi Everyone,

    Is anyone using the 3 sensor setup for Oculus, any success?

    I dabbled with it last night using the default Oculus tool/guide and the results are ordinary, to say the least.
    As usual, the Uberweb is full of guff that descends into fighting between Rift and VIVE users :)

    I just want to see what other people have out there?

    My "play area" is not very large, so I suspect the sensors are drowning each other out.
    I'd be lucky to have a 3x3 sq.m area to swing around in. (Sensors found the space and marked it "Moderate")

    TIA. :thumbs

    Your play area is getting up to what I consider the reliably stable limit for Rift tracking.

    The quality of Rift tracking varies significantly depending on how many cameras are used and there is considerable differences in the robustness of tracking between 2 and 4 cameras: http://ghostline.xyz/publications/Waltz-of-the-Wizard-comparing-room-scale-May-2017.pdf#[{"num":1375,"gen":0},{"name":"XYZ"},0,595,0]

    From my personal testing around 4.2 x 4.2m (around 17.5sq m) with 4 cameras on USB3 seems to be about the absolute Rift roomscale tracking limit, in ideal circumstances, personally I think reliable stable performance is a good bit below that at around 3 x 3m.

    The 10-50sq m tracking volume is really owned by Lighthouse, as the out of the box tracking volume capability of Lighthouse (up to around 50sq m) far exceeds what the Rift is capable of (around 9-15sq m), and Lighthouse 2 will allow more base stations so will improve on the already impressive robustness of large roomscale tracking.

    100% 3 cameras better than 2 here. I have an 8 ft roof :(, all cameras are at roughly 7ft in different corners.
    the setup through oculus is BEYOND HORRIFIC... you basically want to configure it for SteamVR, and when you're in Oculus, IGNORE (you've got to do this) the message when it keeps asking you to rotate cameras or whatever, it will STILL work, and work better than what the oculus app wants to limit you to, it's like @noorbeast was saying, they're trying to limit the space.

    I am NOT sure about the area as he mentioned, as I've never gone past 3x3


    *************Why 3vs2 for me****************
    I do a lot of fitness stuff, and turn around a lot, or play Dead and Unburried and other things where I'm crouching, say even crawling in that one SteamVR demo game (I'll have to insert name later), the 3 cameras means my hands are always tracked, as is the body in general. I do have to say, that at first I don't think I felt a difference, but also know I re positioned the cameras ...if you're not moving in circles or crouching (basically if you're not obscuring a view of a camera often) you likely won't notice a difference

    Thanks, Gents

    @gSeat - I'll try setting up via SteamVR. I actually found that I had to use SteamVR to get most of my room scale stuff working in the past and I had totally forgotten about that option.

    Yes, I agree, the tracking setup in Oculus is not well developed. My setup is the same as you, the cameras are about 7 ft up on 3 corners of the room and pointing towards the middle of my play space.

    I'll post back my findings/outcome once I get the chance to tinker at the weekend.

    Hi Gents,

    @gSeat - I tried your suggestion and let SteamVR do my setup - Thank you. It worked well.
    Kudos to Steam for allowing my Rift access to this setup!

    I love the use of the Portal characters for room setup and the environments in general are heaps better than the Oculus offering.
    Once I set my floor calibration and did the corner trigger thing it all worked a treat.

    I then spent the next 4 hours (I kid you not!) sat on a swivel chair in the middle of my play area just in awe at Google Earth.
    Something quite special about being able to fly to any part of the globe and take a look around.

    If you have not tried it yet, be sure to go into preferences and tick "Always have Human Scale". This scales the maps in relation to your height so that you (in effect) get given a virtual JetPac and can go flying around cities and get a sense of the size of places.

    (eg: Stand at the base of a Skyscraper and look up, or even better, stand on the edge and look down :p )

    It's amazing!

    HILARIOUS!!!!!:grin:grin:grin:grin:grin:grin:grin
    SOoooo true, VR is amazing, and that's like a kind of meditation :) Yes, do similar things every now and then, so fun and random :)


    Great option, you made me think of this add-on, which could go in a FAQ somewhere:
    Open VR Advanced Settings https://github.com/matzman666/OpenVR-AdvancedSettings
    Before modding anything related here, people should back up there settings for steam and pay note to other options though, it is easy to mess things up.

    I use a two sensor setup with the sensors mounted at the ceiling. The mounte is 3D printed. Work's just fine! :D
