I'm using a HoloLens, but perhaps this is a general problem. I first set up several images of my object from different angles and put several Image Target Behaviors into Unity and that worked to get better recognition as they all were being analyzed in parallel. Then I scanned my object with the scanning application and was pleased that it worked pretty well. However, if I changed the lighting of the object, it would stop recognizing it. So I made several scans of the object with different lights turned on/off and tried to do the same thing that I did with the images. I put 4 different object Target Behaviors into Unity and expected that the ones done in a darker room would be recognized when the lights were off. However, only 1 object target is recognized with each build of the application. If I disable the one that is working then another one will start working, but I haven't seen more than 1 work at a time. Does this work with other devices? Will this be supported in future releases?
