Having worked with GrowFX for 3dsmax for vegetation assets in the past, this is my first shot at SpeedTree 9 with custom foliage and bark materials from my 2.5 / 3D scan workflows. This relatively young quercus robur (common european oak) model can be set to 5-8k triangles for the LOD0 stage depending on desired foliage density. The large oak model spans over 20m with 50k tris at the highest LOD.
