I love doing the smaller details. It takes so little to enhance the look of this. Putting on some 6 sided polygon-objects makes up for the bolts. Although my bolts are a little more elaborate, they are still simple. And of course the proportioning of parts is also important to get that "real" look I am going after.

I intend to do a major texture job on this airplane. But I guess I'll use some kind of standard shader on the engine. Just to give the parts some material-color and material-bumps.

I am now going over the engine to delete any unneccessary faces and making the parts one-sided in the attribute editor to (hopefully) save some memory.

I wonder if, theoreticly, that an enclosed poly-cube is less a memory/space "hog" if it is rendered one-sided???
