What I'm trying to do is model and texmap only a half of a complete plane and get the other half by symmetry.

What I found though, was that you have to be very careful with optimising. Sometimes you can get nasty things happening!

Save before you optimise, and check that the game accepts what you have one. I got caught like this on the B24. Each half of the fuse is a different texture, to avoid mirror image issues with squadron markings. Merged them together and lot faces when I optimised!

Let's say you want to create a horizontal stabalizer that has no thickness - like any of my WWI planes. But you do want to texture each side with a different area of the texture map - because you want a different top and bottom texture. You can not use a 2-sided poly here becuase there would be one map, the texture would look identical from both sides.

So I create two polygons that have verts located at the same exact locations, but the normals are flipped. I can now texture map each side correctly. BUT, if I made the mistake of "optimizing verts" then I would lose one side! This is because the process of optimizing finds verts at identical locations and replaces them with one shared vert - not what I want in this case.

This is the one time that you can not optiize, but I do make sure that each half of the stabalizer is optimized... then the two halfs are mergred but NOT optimized...
