First I'm not a 3D modeler and I cant change the geometry of the model. Can I export to a .3ds without smoothing? Smoothing is causing tons of issues in my model (shading issues). I want it to just look like it does when it's flat (when viewing inside of blender). Can this be done?

  • $\begingroup$ Hi, where/how are you looking at the exported model? $\endgroup$ – m.ardito Sep 26 '17 at 20:24

This object is badly designed, imho :) but it surely can be fixed!

I guess it comes from a vector import (cad maybe) but even if blender in solid mode does a decent job of displaying it, this mesh has many flaws. You shouldn't believe me, you should believe the numbers.

Numbers: your model has 70% duplicated verts. A simple "remove doubles" reduces your 38287 verts to 11504!You have 26783 doubles...

But it's not all, imho: in wireframe mode you can even see many weird edges here and there, but to get more numbers, I used the bundled "3d print toolbox", which makes easy to find mesh problems.

Here the result after removing doubles...

Since we know nothing about your "own renderer (OpenGL)" it could be this one to visually show the model weird, probably due to many issues in the model. If you could post a picture of the model in that renderer something could perhaps be guessed...

You can always make faces to look sharp, just select the object, go to Edit Mode (Tab, select the faces and then on the left panel (press T to open it) you can find a tab callled Shading / UV -> Faces -> and click Flat.

  • $\begingroup$ Kaderabek I've tried this but I receive the exact same output. I'll play with it more. What I don't gt is why is what I see in Blender so different than the output? $\endgroup$ – Cjust689 Sep 26 '17 at 19:44

  • $\begingroup$ I attached file to original post. Thanks! $\endgroup$ – Cjust689 Sep 26 '17 at 22:21
  • $\begingroup$ I cant see any, I have exported it to 3ds and imported ... it looks just exactly the same. How can I reproduce the problem? $\endgroup$ – Jan Kadeřábek Sep 26 '17 at 22:46
  • $\begingroup$ Can you upload the .3ds to me? We are using our own renderer to view the .3ds file. Example if you open my original blender file exmaple.blend in Blender. If you select all the faces and set the shading/uvs to smooth. You should see the issue I am getting when I export to .3ds and bring into our software. $\endgroup$ – Cjust689 Sep 26 '17 at 23:04
