I have downloaded the latest version of the hololens sample from Unity store. My Unity version is 2017.3.0f3. For all the image targets (astronaut, drone, oxygen and fissure) I have enabled extended tracking. I printed the targets in A4 and cut them out separately.
I followed the standard hololens build setting (universal platform, D3D) and player setting (XR settings -> both VR and Vuforia AR checked). In the Vuforia configuration, I have added the license key, and used the default settings as done in the sample. Both the VuforiaMars_Images databse and the VuforiaMars_VuMark database are checked and activated.
When press the play button in Unity editor, it shows a black scene, and on the console it says the Trackable objects are found. I tried both the Unity remote app on hololens and actual deployment through visual studio, as in the Unity play mode, nothing is shown in the scene. Then if I display the printed target images, nothing shows as well.
Could anyone give me an idea of what might gone wrong?
