Alpha texture problems

I have been using Speedtree for a while now with Unreal and the results are brilliant when working with generic broadleaf trees however I am finding when using Pine trees the individual needles tend to appear clumped together within Unreal. I assume there might be a material parameter somewhere to get around this but I don’t know where to start.

Here is how it looks in Speedtree:

As you can see the gaps between needles is perfectly defined and looks well.

Inside Unreal:

If you bring the camera really close to the alpha then the detail comes back but you do have to be very close:

Keep in mind the LOD’s haven’t yet been enabled so my only other thought is it could be Unreal’s occlusion?

Please help!!
