How do I fix this?

[a random squirrel]

I am using a mod to make a shuttle but one of the wings is upside down. I can tell because it has the silica tiles texture. How do I fix this?

Hello, and welcome to the forums! 

Kinda hard to answer any questions without additional information, but I'd say your best bet would be to go to the KSP forum thread (in Add-on Releases) for whatever mod you're using, and ask your question there-- that'll be where the people are who would best know how to answer your question.

 

(Also, moving this thread to Add-on Discussions.)

Or you can provide a screenshot from the SPH.

Most likely the problem can be solved by place the wing on the other side of the craft and mirror symmetry should place the counterpart right side up.

You were probably using radial rather than mirror symmetry when you added the wings. in the VAB/SPH you can switch between them by pressing R. The symmetry indicator bottom left will change to tell you which mode you are in.
