[Solved] Problem of MAN SD200 (1977)

[Updated at 6th April] Finally, I fixed it by using MSPaint, the mirror texture is from "SD77_02.bmp"

What happened? (also happened on "Cosy-Wasch" and "Drospa")





but there are no any problems when I choose banner advertisements or "Beige"

It looks like the makers of the bus have forgotten to assign a texture to that part in the 3D program.

No, this is a texture bug that unfortunately has slipped through. The mirror area is not included in the texture files for these "full" liveries (the liveries were created before the upper deck mirror was built, so it's not included in their texture).
