Painting and to put decals on the vertical stabilizer, and also the wings.

[HJKasper]

If I want to put a decal on the vertical stabilzer, it is shown as a mirror image on the opposite side. This also applies to labels, which are then also shown as a mirror image on the opposite side. For example, how can I paint the vertical stabilizer in two different colors? What was iniBuilds thinking here? Did they want to save space on the texture T_T33_EXT_1007...? How can I solve the problem? Please answer this. Best regards.
