I imported this model from blender as an FBX, with no real problems (Other than animations edited in UE4 not updating in the skeletal mesh) but as you can see here, the mesh randomly flickers when the camera moves. How do I solve this? Reimporting doesn’t work, I’ve tried
Hey there, that seems to be some type of z fighting, do you have double layered mesh?
how do I find that out?
you would have to go back into a modeling program like blender. In blender you could go into edit mode and select a face and press H to hide it. If you do that but still see a face where it was then there is extra polygons and you probable duplicated the mesh at some point
What ThompsonN13 said 
There is a single layer of mesh. What now
If you set it to a simple white material do you still have the issue?
Yes, I even tried a separate project and No vertex color data. Sorry for the late reply.
can you post your model itself so we can try downloading it and looking at it?
the mesh you linked is not the one from the picture
