  3. Rename the created database
    1. In AugmentedImageSessionConfig pick the new database through the Augmented Image Database public variable

WORKAROUNDS (IF ANY)

Changing the file ending from .JPG to .jpg.

Thank you. Spent 40 mins trying to figure this out.

The issue is caused by arcoreimg binary which actually builds AugmentedImageDatabase. arcoreimg.exe build-db --input_image_list_path=/path/to/image_list_file.txt --output_db_path=/path/to/myimages.imgdb

the image_list_file.txt contains lines like this: mouse|path/to/mouse.png|0.1 little dog|/path/to/dog.jpg

Each line represents - name | file path | (optional) physical width as float

If something is wrong with any parameter like file format, float having comma "," instead of dot "." - happens for instance in EU countries due to default toString() in case of float - then the database is not created/update and images are not recognized by ARCore.
