Target image works fine.
I set up a vumark which passes the tests. I set up the database and downloaded and all looks good. Play via my iMac camera and it will not pick up the vumark.
I can use the image in the viewmark as a target image and that works fine so I verified the image by saving it as a jpg and creating a new target image project.
I read that you enable Track From Appearance on the vumark but that cause Unity to crash with the attached error (see image).
I am using Unity 2017.1 and the Vuforia package 6-2-10
I have started with fresh projects for the las 3-hours but no luck in fixing this. Also once the crash occurs you have to create a new project as even cleaning the current one the crash still happens
Any help would be great as its killing me
Unity project attached - feel free to use
[Edit] any box you tick in the vumark behaviour component crashes unity with the same error
