I have a weird error. I added a pillar to my scene with approximately 17k vertices and in every mode (lit, unlit, play…) it’s always facing the camera, when I move. Like in old 90’s 3d Games…
I don’t know what’s wrong with it.

It looks like your mesh has flipped faces. Does this same effect appear when you look at the mesh in the Static Mesh Editor? To fix this go back into your modeling program and select your faces and flip (this will reverse the normal direction and should correct your problem.
