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.
Vuforia works on webcam but not Hololens. Help?
We are trying to use an image target to place a hologram using Vuforia and Unity. When we connect a webcam, our model appears above the target. However, when we deploy the app to the Hololens and hold up the printed target, the model does not appear. We know the app is deploying because we can see other holograms in the scene, but the HL does not appear to recognize the target.
We used a custom database for our image target, and we set the dimensions in the database to a width of 0.0745 (meters). Our real-world printed image is 0.0745m x 0.0745m.
We have tried adjusting the clipping planes, disabling Vuforia play for the webcam, removing the Vuforia SDK from the list of VR SDKs under Player Settings, and physically moving backwards and forwards while wearing the Hololens.

Do you have any other suggestions to try?
