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.
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?
