Welcome to GTA5-Mods.com

@Sir_Angus hello, sorry for the late response. The original file is located in this folder: C:\Games\Grand.Theft.Auto.V\update\x64\dlcpacks\mpsum\dlc.rpf\x64\levels\gta5\vehicles\mpsum.rpf\
but like always i recommend to put it in the mods folder, for example:
C:Games\Grand.Theft.Auto.V\mods\update\x64\dlcpacks\patchday28ng\dlc.rpf\x64\levels\gta5\vehicles.rpf\
Greetings : o )

@TopcityPD hello, is it possible that you can make a video which shows the problem?

@FadisoN Hi FadisonN, I would like to know how you keep the files so small, so how do you save them, after you created them? Thanks : o )

danke dir : o )

@skream07 hello, could you please show me a screenshot?

@Starfox1993 I´ve got this one, but you should know it because you commented it. I guess you mean another building.
