Issue with 3d Objects After Import from Blender

Unity Engine
1

Hi guys,

Please refer to the following video:

I basically downloaded this 3d United States map, where each state is a 3d object. As you can see, in Blender, every state looks solid. I am not familiar with Blender enough, but each state has a parent object and then a data object? Anyway, i noticed that if I select the data object portion, it will look hollow when i scale it up and down.

After I import it into Unity, I noticed that some states like CA, looked hollow and some states like Arizona looks normal. Could someone shed some light on why this is the case? Was something not correct when I converted it or imported it into Unity? Thanks in advance.

Check your normals in Blender, they are inverted. To do it, select your object, go into Edit Mode (tab), select the face and press Alt+N to inverse the Normal.

Thanks!

So I actually figured it out. After i import the 3d model into unity, I click on it and look at it in the inspector. I switch the Normal mode to NONE. And apparently that worked. Still not sure why, I’ll have to read up on it.
