    Exporting to OBJ problem :(

    Does anyone by any chance know why after you export a static mesh out of a map into an OBJ and then import it into a 3d application the model becomes jaggy, and less smooth. Here is an image I took of when I exported the mesh into an OBJ out of Unreal ED 3.0.

    Now here is what the mesh is suppose to look like.

    I would really like to know how to fix the mesh in the first picture to look like the mesh in the second. I have tried converting poly's to sudivs and sudivs to nurbs and everything else and all I get is a bigger mess of a broken model.

    For one, no verts are welded when you import. Two, smoothing groups are lost.


      Would I have to merge every verticy manually or is there an easier way? Anyway thanks for the help Angel
      Ima take an extra look around when exporting things.

      I'm sorry I didnt mention this before but. Instead of exporting it as an OBJ out of the editor, I exported it as an STL for the second picture. This is why that one is smooth and the first is not. However when I go to texture the good looking one my model becomes some what transparent and the texture does not show, I've never had any problems texturing anything amongst any other model in the past except the one on the second picture. The first one textures just fine, but the second becomes transparent for some reason. Here is an image of what kind of transparency I'm talking about.

      At any rate, which do you think would be less of a hassle to fix. Fixing the one I exported as an OBJ or the one I exported as an STL.


        If you are exporting from UnrealEd to obj or stl and importing that into Max, simply select all relevant vertices for each object and do a Weld, and select all relevant faces and set the smoothing groups accordingly.
        If it is a single object just do a select all (verts and weld, faces and smooth).
