hi. i worked with vuforia package a few years ago and i didn't have any problem with virtual buttons. its implementation was easy and worked nice. but after a while i came to use the new package for my new project.
vuforia version 8.6.10
i implemented virtual buttons as it's in its "vuforia core samples" on asset store, with my instant image target. ran it, didn't work.
then i deleted my project, opened "vuforia core samples" project, opened VirtualButtons scene, changed the type from DataBase to from image and replaced the target image with my own image. build it. doesn't work again.
note: my target image was tested, and can be tracked.
seems virtual buttons doesn't work with instant image? or i'm doing something wrong?
