Why am I getting an asset error TileLines[1].jpg?
That error seems to have happened from one version to another in C4D with content browser changes.
Here is the fix:
In the "Preferences" menu click the "Files" column.
In that window, in the first available slot, copy and paste the line below:
preset://gsg_city_kit.lib4d/tex/
Here is an example.
That should do it!
