Oak Oak Pine Large - this Blended Background should be used with my Oak-Pine wide cover spline or these trees which make up the spline: Black_Oak, E_WH_PINE, Emory_Oak_15m, Loblolly_Pine_2, Red_Oak_10m, Scarlet_Oak_15m, Shagbark_Hickory-1_15m, Shagbark_Hickory-2_15m, Shortleaf_Pine_10, Undergrowth_6-2, Water_Oak_20m, yellow-poplar_3. I used built in British ground textures in building the backgrounds and they should match the background pretty well. There is a tutorial on my site about how to use this Blended Background to best advantage.
