I started developing an application by replacing the teapot in the ImageTargets sample by my own 3D models.
Now I want to use my own trackable. For this, I created a PNG target and downloaded the Unity package (with 0 bytes size). I tried to import it from within my Unity project but received an error as 'Error while importing package: Couldn't decompress package'.
I also tried to use the zipped version containing config.xml and qcar-resources.dat by copying them to Assets\StreamingAssets\QCAR. Then I changed the material of the ImageTarget prefab in my project with the new one. But I am not able to see any 3D augmented content after running the application on my phone.
Using a JPEG to create a trackable is still giving problems.
How exactly should any customized trackable be incorporated in a Unity project?
