Here is an interior from GTA IV ported over to V. We used this in our server but eventually removed it, and it’s been sitting around doing nothing. There may still be some small bugs overlooked, however, enjoy!
(note, files may be locked still because I lost the original files.)
also having this issue, you can clearly see the exterior from far away but the moment you get close it goes back to the original building, you can still enter but shows the original building on the outside
