Ok I just want to share this with anyone who is having the Blue blocks not loading in. Go to X-Plane 11--Output--Preferences. Then go down to your X-Plane PICS Rules File. Open it with notepad or whatever you use to edit your scenery pack file with. once you have opened it scroll down to renopt_planet 1. Now edit it to renopt_planet 0. you may need to do this ecah time you dump your Preferences. Hope it works as well for you guys as it has for me.
regards
Martin.
