Any experienced modelers around?

[The chaser]

So I was working on my tram model. And I tried to export all the parts but I found out that some textures where on the other side of the model. Is it possible to flip over the textures and how do I know what side the texture will be on when I make a plane for example?

I'm using Maya 2010 btw.

I did try to just use the scale tool to switch the whole model but that messes up the lightning.

Could you please upload a screenshot of your problem? I don't quite understand the problem

I think you are talking about the normals though: You are in maya so I don't know how it's done, but I guess flipping the normals in the problematic parts will fix the issue.
