Hi @taghdir Vuforia just released in 8.6 Image Target at Run-time. You can find more information here: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/how-to-create-and-load-targets-in-unity.html on how to use it. Thank you. Vuforia Engine Support

I am not sure that Unity is allowed to access some folder directly. I guess you have to use a filechoser dialogue to load stuff in unity and handle it there. Not sure about filebrowser apps though.

Thank you
I tried to set the image targets at runtime based on:
https://library.vuforia.com/content/vuforia-library/en/articles/Solution/how-to-create-and-load-targets-in-unity.html

And part: “The code example below will allow you to download a texture image from a web URL and generate an image target from it.”

But I have the RuntimeImageSource error in this line:

“var runtimeImageSource = objectTracker.RuntimeImageSource;”

my error is :

‘ObjectTracker’ does not contain a definition for ‘RuntimeImageSource’ and no accessible extension method ‘RuntimeImageSource’ accepting a first argument of type ‘ObjectTracker’ could be found (are you missing a using directive or an assembly reference?)

My code is attached
