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.

Unity Camera FOV?

I'm having trouble understanding how the Unity camera Field of View setting relates to the HoloLens FOV experience...

I want to set my Unity camera FOV high (60) because it gives a good perspective and you don't get zoomed in on everything. However the official HoloLens Unity camera has a FOV of 16 which is too zoomed in for my game.

Do I have to use a FOV of 16 because that's what the experience in HoloLens will be like?
Thanks.

    Hi, @kenhes, and welcome.

    Concept of manually changing fov in a mixed reality app is meaningless. The rendering is driven by the real environment and the hardware. Changing fov would be like swapping your eyes, changing distance between them, etc. You should treat fov as a read-only runtime value and adjust your visuals according to it.

    However if you want to get in-Editor or in-emulator experience close to that on HoloLens I believe setting camera's fov to 16-17 degrees would do the trick.

    This answer should help:
