Welcome
(to the completely desolate) OFPEC
You have to also "link" to the texture from the original model, the texture that has the interior and the wheel rigs and such:
"A3\Air_F_Beta\Heli_Transport_02\Data\Heli_Transport_02_int_02_CO.paa"As in add that as the last texture after your own textures in the
hiddenSelectionsTextures[]The amount of textures you have in that array has to correspond the amount of hidden selections on the model, in the exact order:
The model in question has 4 hidden selections:
hiddenSelections[] = {"camo1", "camo2", "camo3", "camo4"}You have only three textures defined so they only cover the selections camo1, camo2 and camo3 leaving camo4 without any textures => missing gear and stuff.
Oh, and btw, you should register a
TAG and use it with the chopper class name especially if you're gonna be using that thing publicly.
