Texture repeat on read only objects.

v4.3.stable.official

I’m unable to set texture to repeat.
Other guides have been able to set it in the inspector tab, but for me it gives an alert “This object is read-only” and “This resource was imported, so it’s not editable. Change settings in the import panel and then re-import.”
Is there a way to make it not read-only?

You might be able to right click the resource an “Make Unique” or as the alert says, find the texture in your Filesystem tab and change it’s import settings.
