Ponderosa Pine Large - this Blended Background should be used with my Ponderosa_Pine wide cover spline or these trees which make up the spline: Apache_Pine_1, Douglas_fir_14, Incense_Cedar, Jeffery_Pine_3, Ponderosa_5_35m, Sugar_Pine_2, Utah_Juniper_6, Utah_Juniper_7, White_Fir_7. 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.
