So I’m just learning both blender and UE4. I tried to import some low-poly pine trees I made but when the player looks at the model, the faces closest to the player disappear. the faces will all appear and disappear in order to maintain the look. Its a bit hard to explain, so have some pictures

As you can see, no matter where you go you can see into the objects as the faces facing the player disapear. the last image shows what the trees look like in blender where they were created.
