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 large is the cache of HoloLens Spatial Map?
If I understand correctly how HoloLens Spatial map works, when HoloLens is on your head, it constantly scan the environment and build the spatial map. In Hololens Windows Home(the default view of Hololens), You may place objects in the environment, what happens in the background is that it creates WorldAnchor and attache the object on it. You may walk quit far away or go to somewhere else and when you are back you can find the object still there, because the spatial map of the area is already cached inside HoloLens. The question here is: HOW LARGE is the cache? Is it so that when the cache is full, the new map will replace the old ones, in that case, your anchors will be lost and your objects will NOT be visible there?
