NASA's High-Altitude ER-2 Research Aircraft

For Lockheed U-2R.

Once installed according to their instructions, open the dlc.rpf with OpenIV.

Follow this path to the file to overwrite:

...GTAV/mods/update/x64/dlcpacks/warpackusa/dlc.rpf/x64/levels/gta5/vehicles.rpf/u2r.ytd

If you wish to retain the original black USAF livery, while in OpenIV, extract the file u2r.ytd. I typically extract the original .ytd to the same folder as the dlc.rpf and rename it to origu2r.ytd.

When ready to overwrite with NASA U-2R livery, toggle "Edit mode", top right button, and drag u2r.ytd from the extracted zip file and drop here:

...GTAV/mods/update/x64/dlcpacks/warpackusa/dlc.rpf/x64/levels/gta5/vehicles.rpf/u2r.ytd

Just to confirm the livery, I'd click on the u2r.yft file to open the OpenIV Model Viewer to see what the model will look like with the new livery.

Once satisfied, close the model viewer and run GTAV and spawn bone with the trainer of your choice.

Enjoy,
Gillman
