Hollowing out a primitive.

Im trying to make the inside of the 2nd Death Star, the big room where Lando & Wedge shoot the generators causing the Death Star to explode, and I was wondering, is it possible to hollow out a cylinder so ships can fly within it but still see texture from the inside?
Im starting to come back to modding, and I've forgotten a lot of stuff. I feel uber-noob.

assuming this is once you have entered the Death Star and the cylinder no longer needs to be seen from the outside, just select all the polies and go Invert Polygons

Thanks.
So once I click Invert Polygons, are the black sides the sides of the primitive that will show no texture from 1 side and are viable to go through?
I clicked on the cylinder, then I clicked invert polygons, and the top inside of the cylinder turned black while the bottom & side inside turned grey.

Which would mean that you turned around every polygon.
Try and only select the 'inside' polygons and invert these. (Obviously you should invert the cylinder back again to the default setting.)
Or maybe it was a successful result
Personally, I would delete the 'top and bottom' sides, since you want the vehicles to fly through.
The reason why they turned grey and black could also be the lightning, and it now just reflects the opposite way than before. try and throw on a texture or something so you more clearly can see if the surface is showing the right way.

What i suggest, delete the upper and lower poly's, duplicate the rest, scale them a bit smaller, invert them, then bridge the edges on top/bottom..
Then you have a hollow cylinder

I got the impression, that the hollowed cylinder was a fly-through, which means that he has no need for a cylinder with a hole in. Hence, most applications supports to hollow primitives on creation anyway. He wants to control which way the surfaces are visible.
- an even lazier, maybe someone like me, would instead make the entire polygon two-faced and spare out any other step than this first
Lovely how many ways there are to reach just one result, isn't it? Follow your heart's desire and tell us if you're satisfied
