Got this?
It looks like the surface normals are facing the wrong way. These are what defines what side of the mesh is the “outside” Typically its preferred to calculate one side rather than both because its less for computers to process. You should be able to flip them somehow.
Good luck

I see you got the left half with inverted normals, it is usual with mirrored models. Enter Edit mode, select all and press Control + N for setting all the normals of the model looking to the outside. Maybe you will also need to select some faces at the center of the torso (those seen in wireframe on your picture) and manually invert their normals too. You have an option to see the normals graphically in the buttons window in edit mode.
I hope it helps you.
If it isn’t an issue with your normals it appears that your model is so big that it’s being clipped by the camera settings. If so, try scaling the model by 0.1 (or even 0.01) and see if that works.
thanks guys!
