Blender imported mesh not rendering properly

[anonymous_user_3a2edf49]

Hello, i made this tree in blender, but i got problem that its “root” and “body” gets drawn based on camera angel.

As you can see on the next pic, it looks like its one sided from diffrent angels.

I added little point light btv…

but in blender, its perfectly two sided:

is something wrong with UE4 or Blender, and how can this be fixed?

You have to flip or recalculate your normals in blender, before exporting.

You find this in the mesh menu.
