I've encountered a texture bug and I have no idea what causes it.
Here are some screenshots: https://imgur.com/a/bGO1Oi1
I've checked the yft and ytds of the affected vehicles, double checked my vehicles.meta, replaced the carcols.meta, carvariations.meta
This happened after I installed the Ultimate British Car Pack oIV package, and even though I've already restored the original police car, sheriff, FBI, polmav, yft and ytds, it still shows the modded police cars.
@Spirytus looks like a the .ytd file for trevors truck is getting messed with. check the patchdays for any ytd's for his truck (don't remember the name of it lol sorry) that could be clashing
I made a mistake, I thought there was only one vehicles.meta file for all DLC vehicles and I piled them onto the one found in update.rpf instead of their respective dlcpack meta files. Thank you the problem has been solved.
