There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
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.
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, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

Hologram Min Range
According to the documentation, spatial mapping min range is 0.8 M (up to 3.1 M) while the min optimal range for holograms is 1.25 M (up to 5 M).
Will holograms appear at a shorter range or do they automatically disappear? The documentation suggests that the app itself should programatically fade virtual content closer than 1.25, which suggests they will still appear at closer ranges I just wanted to make sure.
I ask because the documentation also says that we shouldn't try to design for direct interactions between users and holograms -- but the Meta 2 allows this and it would be really cool to try, anyways.

The device will render holograms to within .1 M away.
In our research, holograms that are at least 1.25 M away are comfortable for a long time for almost all users. It is reasonable to have short interactions that come as close as 1 M away.
Trying to render holograms closer than this tends to produce discomfort for users, even when viewed for short periods of time. This response will vary based on the user, and their susceptibility to a/v conflict.
Because we believe that developers should be building experiences that will work for as broad a range of people as possible, we strongly recommend that you follow the design guidance referenced above. It is the result of extensive testing and research.

As holograms get closer to the user, accommodation/vergence conflict increases. It is possible to render holograms somewhat closer than the recommended distances, though doing so will not produce a great experience for all users.
Is that true across the board? I'd think it would depend on the experience that is being built.
Just to clarify the question though: will holograms appear at all short range distances unless the developer fades them out?
