I'm trying to make a model of a gun in Blender. There is some engraving on the side, every thing has been going relatively well up until now, I keep getting these weird shadows no matter how I arrange, delete, or add vertices. It's not triangles, I have tried using lots of triangles, and no triangles, it's not normals, it's not texture, wtf is wrong with my model? It goes away in flat, but I need it to be in smooth.

Here is the part of the model I am having trouble with

And a closer look at the most troublesome spots
1 is the strangest, and hardest to get rid of that I have found, 2 and 3 are easer to get rid of, but when I get rid of one, all of the previously good polygons go wonky.

Oh, and before any one says anything, there is only half of what I am working on because I was going to mirror it after I get this problem fixed.

Are the dark polys inverted or facing inward? Or are there two coplanar polys in those dark areas?

Converting from one file format to another and back might fix mystery problems too, like export to .3ds or .obj, the import that back in.

Right section, it's art. Do not move this thread. Computer graphics are just as real an art form as any.

Could go in either forum, but agreed. It isn't exactly the "wrong" forum.

I tried flipping them, it messed up the one's next to it, and when I fixed that one, the first one changed back. Nope, not that ether.
Changing formats didn't work ether :?

Found a fix, posting it for any one else that has the same problem. Modifier > Edgesplit. Doesn't fix it in edit or object mode, but it fixes it when rendered. And it slows the computer down quite a bit, so ether apply it just before render, or make it visible only in render (though it doesn't fix it pre-render, it does tweak the mesh).

you probably have already tried this, but going into edit mode and doing ctrl and N recalculates normals and can sometimes sort out shading problems

Lady's and gentlemen, I present to you, the Lasseter Model 7 Special Edition. Despite being 17 years in production, it is, and more then likely will continue to be regarded as one of the best designed laser handguns in the last 100 years. Designed and produced by the eccentric Outworlder clan Lasseter, at there weapons manufacturing plant in *Location unknown*, it has been Lasseters most sought after guns to date, despite only 1000 of the Special Edition every being produced. Featuring a 150 shots per power-cell, 12 power settings, 2 bore settings (1/2” and 4”), a cutting beam (rapid low power burst designed to cut through armor, walls, and other obstructions), a built in scope, range finder, and distance compensation, it is believed to strike a superb balance of features and usability. It is manufactured with a carbon fiber body and handle, and titanium barrel casing, it is durable while maintaining a wight of only 3.5 pounds when loaded with a standard power-cell.
