Temporarily it is only possible to enter the interior with Menyoo “GTA V Trainer”
This project is not 100% finished
This mod may not be compatible with MULTIPLAYER MAPS in SP! (at least for me)
I do not have time to deal with the problem more intensively, if you have the solution please let me know.
1. Run OpenIV
2. Drag and drop the folder “sml_lux_apa_1b” in the following path “mods\update\x64\dlcpacks”
3. Go to “mods\update\update.rpf\common\data” open “dlclist.xml” and add the line “dlcpacks:/sml_lux_apa_1b/”
4. Drag and drop the file “sml_lux_apa_1b_portals.xml” in the following path “menyooStuff\Spooner”
