Hi frame_th,

You cannot simply change the texture and expect it to work.

Please read the sdk guidelines here:

Look for Swappable Datasets under Mastering Advanced Topics.

There is  no sense in changing the texture of the marker itself, as it doesn't get rendered in the final app and only exists as an orientation point. If you want to still render the marker then you better make a plane object with this specific texture. You can do this by highlightning the planeobject and just drag a texture into the inspector.

Maybe you can tell us what your goal is to better underrstand what you want to do.

Also remember, that you have to activate the according dataset on the ARCamera Gameobject and the Imagetarget.
