I am a noob but learn quick. I downloaded a 3ds model from celestia of the space shuttle atlantis. It looked good in my 3d viewer but when I opened it in blender They cylinder tanks were very blocky. Not round and smooth but like many sided instead. So I opened it in 3d max and there were a lot of errors which I fixed a pick with poly convert and the model looks ok but not smooth and realistic like the shuttle and tanks should be. I also converted to obj and same result. I tried some smoothing in the modifier tab but I cant figure it out and I really want this to turn out realistic and nice. You guys all seem nice and helpful on here so I thought maybe someone would be so kind as to help out a noob. I am still learning all of the lingo. I would like to be able to fix this in max without reconverting because I had to already fix the errors in the model.

Hello,

Check that your model's Vertices are welded together. If you're unsure, apply a weld modifier to the object and set a very low threshold. See if the smoothing changes visually. Adjust the weld threshold as needed.

If that doesn't help, check that your Normals aren't broken. To check, apply an EDIT NORMALS modifier and see if all the handles are green instead of Blue.

If this is the case, then you'll have to weld those handles where you want the object to look smooth. Be vary, you don't want to merge the handles at Sharp edges or corners (those areas you don't want smoothing to be).

Please post a picture of your scene if this doesn't help.
