Using OBB Expansion Files with Vuforia

Has anyone been able to successfully use expansion files with Vuforia?

I’ve managed to get the OBB files to download and work but then nothing augments from the tracker, even when I use an extraction script to extract the dataset.

If anyone is up for helping or discussing this matter I would be very grateful

I can provide more info if needed (scripting etc)

Can anyone help me? To see the progress I’ve made, see: https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/dataset-does-not-exist-error-when-using-unity-4-android#comment-2044266
