UE 4.20p4 ARCore image database cannot build.

@Hermyth I just tried with normal images. If it doesn’t work, likely your images aren’t complex enough.
To double check go to:

Make a copy of CMD and put it in:
EnginePath\Engine\Plugins\Runtime\GoogleARCore\Tools\Windows

Then type: arcoreimg build-db --input_images_directory=/path/to/images --output_db_path=/path/to/myimages.imgdb

You will see if it works or fails due to complexity errors. If it works, than just build the game as normal

I just copy the tool folder with arcoreimg.exe from the git version of ue4 to the ue4.20p5 and its work fine, not need cmd line.
