I'm using Unity to develop android app.
In the user-defined target sample, after clicking the green button to create a UDT,
it seems the sdk will capture the whole screen to create the UDT, but it may capture a lot of irrelevant parts .
Is there any way I can select part of the screen instead of using the whole screenshot to create a UDT?
Besides using part of the screen to make UDT, is it possible to use an image file (such as a photo in the user's album in android) to create UDT?
