they haven't been updated in a while but checked with the most uptodate version of the empire mod, 2.3, just incase & its loads fine. maybe you have downloaded a older version of the mod?

No, I don't have them. Could it be that the floors in the mod no longer exist or have been renamed?

the mods needs are those listed in the box right above this comment section ↑ , & those listed in the REQUIRED ITEMS tab above. just checked & the hangars floors, walls, & roofs all come room the same mod, the "empire" mod, so if your seeing any hangars at all then you shouldnt be missing anything. make sure you toggle off vertical mode & surface snapping as show in the last pic. if your all talkin about the landing stripes & whatnot as seen in some of the pics, that is from a older version of the golans model that had hangars built in but had clipping issues so they were removed

@turfy i have the same issue

Could you please tell me again exactly all the mods I need to complete this composition?

Yes I have, but some floor panels do not exist, like the ones in the hangar

make sure you have all the required mods listed in the requirements & description

I have no floor panels in the hangars for this composition
