Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

How many HoloLens can view a project at one time

Hi guys,

Was wondering how many HoloLens can visualize the same gameobject at the same time? I haven't tried. but wondering if anyone has experienced a limit or is it unlimited to the network?


  • It depends on a variety of factors.
    1. Environment: In a well prepared environment with ideal wall and floor colors (medium/dark gray, patters and a couple of real objects) up to 5 HoloLens can be used at the same time. Tracking stays very confident and stable.
    2. Network Quality: The HoloLens works best in a 5Ghz network with little to no other Wifi networks in the vicinity and same Wifi Channel.
    3. Sharing Type: When you use sharing with UNet, the actual footprint of data being shared is suprisingly low. All the „heavy“ data (Models, Textures etc.) are part of the app. Only the position, orientation of each HoloLens and probably Holograms are being shared. Additionally some custom command data (interaction with object A at postion B etc.) will be send.

    If you try to use Holographic Remoting and/or Mixed Reality Capture in the same context, you will be limited to 1 or 2 HoloLens because the traffic is much higher and the overall performance might be an issue as well.

    To give an example: I worked on a project whereby we created a shared experience with 5 HoloLens and additional clients in the same Wifi and physical location. It worked perfectly fine as long as the users did not „run around wildly“

    I hope this answers your question.
