Speedtree Branches Lighting Issue

Hia! So I’m trying to wrap my head around SpeedTree in Unreal 4 and I’m having some lighting issues - which I’m guessing are somewhat related to normals? I’ve previously created trees in Maya successfully - but I’m getting some strange, ugly shadows in my new SpeedTree ones.

Here’s an image with the bad lighting. In the foreground of the UE4 shots is my new tree, and in the background you can see my Maya trees that look much smoother overall.

I’ve tried messing with the normal settings under “Lighting” in SpeedTree but all varieties of the settings seem to do little.
