I made textures, but don't know how to properly pack them in an addon properly

[pognivet 150]

I edited the ural fuel truck and gaz-66 ambulance from RHS to have farsi/persian writing instead of russian and changed the red cross to a red crescent.

 

I have the textures in .paa format, but I don't know how to put it together into a pbo addon where they can be selected as a texture in-game.

 

I also don't know how to disable the RHS script that adds roundels and number plates to the vehicles.

 

I can make good textures, but trying to put an addon together and have it work is esoteric to me.

 

No matter what tool I pack it with I never get texheaders.bin.
