Exporting from Blender to Unity problems

Unity Engine
1

Hey there fellow gaming devs. I have a problem with the exporting process, and hopefully you guys can help me out along with others that may be having the same problems as I do.

My problem is that when I export a model that I am working on (A arena) to Unity 3D, I notice that some of the walls and faces are missing. Also all of the edges are smoothed out. That is not what I saw in Blender while I was making it.

So my question is, can I fix it? And if so, how do I fix it? I have put a lot of time into this arena and I would hate to see it go to waste. I believe I know how to explain what is happening to the missing walls.

Make a Torus in Blender, then make the size 30. Go into that Torus and look at the inside walls. Notice the walls there? Good, now export that Torus to Unity 3D and look inside it again. Did the walls inside disappear? Well, that’s what’s happening to me anyways.

So, how can I fix this effect? Because it would be hard to fix if I had to replace all the missing walls that are already there in Blender, you know what I mean? Any ideas would be welcome, but keep in mind I am a noob to both Blender and Unity, so please explain in detial so I will hopefully understand (And others can too).

Okay so in blender when you create for example, your torus, it will show both faces of the mesh as something visible, but in reality only the outside of the mesh has visible faces, the inside does not, this is for performance reasons mostly.

However there is a simple and easy solution, to the right side of blender click on the icon of a wrench, then click on add modifier, solidify, then simply hit apply, when exported to unity it will show the inside just like you wanted.

You sir, are a God send! :smile: Thank you for the great explanation, and it worked like a charm. Also, do you know how to stop everything from smoothing out? Or does the solidify modifier work on that as well?
