Bugged Viewport?Bugged Normals?

Hello Comunity i have a problem…I want to import this Armor into the Game engine but it behaves weird. UV Map is fine ,the green is flipped.Pic nr 1 shows how its supposed to look like…and there are 2 ways how i can force to show it like this. 1. if i import it as a whole scene.Or 2. if i go to edit->Attributes->Normals and turn of recompute normals.if i apply that it doesnt work. it shifts back to Picture nr 2. IF i do recompute normals it results in Picture nr 3. i want 1. Does the base setting for 3rd person game have simplified viewport or something? Im on my knees and need help.

PS: I dont know how to upload the file id love to so i can help faster
