Okay I did it again and it doesn't work, Im sure that Im losing one step or something, Im spaniard and sometimes is difficult for me to understand the english Thats what I did: 1. In x64e.rpf/levels/gta5/vehicles.rpf I added the new vehicle (a copy of police3) with the "sheriff3" name. 2. In common.rpf/data/levels/gta5 I edited the vehicles.meta file adding the new item named "sheriff3" And the interior texture: 3. Finally in update/x64/dlcpacks/mpchristmas2/dlc.rpf/common/data I edited the carvariantion.meta and added the new item *I tryed too with mpheist*After that, as it doesnt work, I tried to Rebuild all the .rpf files edited. Thanks for your time and help, I hope someone can see that what im losing.
