Importing Model Problems?

As shown in the image below I am trying to import fbx files, I’m also searching FBX import problems for answers, and I am getting these see through walls which as you can guess aren’t very helpful if anyone knows a fix would be much appreciated.

that would be a “normals” problem, make sure you re-calculate the normals for each mesh before exporting.

it also helps if you state which 3d software you are using

I am using 3ds and am relatively new to it would you be able to link some documentation or a video explaining how to re-calculate the normals?
