unfortunately we had to temporary disable the samples in our current release. However, they're still available in the 9.10 version of our SDK which you can find here.
The samples will be available in the new 9.13 version again which will be released in the near future.
With best regards,
I have been trying to download the Wikitude Unity SDK 9.12.0 Expert Edition. When i download and import to Unity 2021.3.17f1, I am unable to see the Sample projects or any prefabs. I cannot even find the Wikitude camera.
