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.
Clearing HoloLens Application Cache?
I am building a Unity application which allows me to load OBJ models at runtime from HoloLens storage. At this stage I'm just keeping them in Unity's StreamingAssets path. I am able to load the models, however it appears that if I remove some models from the path the HoloLens will maintain them in the cache.
For example, say I have 2 .obj models in a directory 'StreamingAssets'. I load the application and successfully import the two models on a button press. Now I remove one of those models from the StreamingAssets directory in the Unity project and do a complete rebuild (deleting the existing VS solution), and redeploy. When I start the new build, the same two models will be loaded.
I have tried uninstalling the application from the HoloLens as well but this doesn't seem to make a difference. I also want to be able, in the future, to update the model directories even it means replacing the whole application.
