After following the installation instructions first in German and after in English I still miss the ground textures at LMML.
I have placed the LMML files outside and added the location info at add-ons.cfg as attached.
The link at P3Dv4.5 add-ons looks correct.
Also the pointer to Malta_Ground at P3Dv4.5 Scenery Lib looks correct.
I guess it is a problem with a miss link at xml or ...... But I don't know really.
Appreciate any support to fix the issue.
