Aspen Birch - this Blended Background should be used with my Aspen-Birch wide cover spline or these trees which make up the spline: Aspen_10, Balsam_Fir_10, Balsam_Poplar_10, Balsam_Poplar_12, Paper_Birch, RedMaple_Summer, Undergrowth_6-2. 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.
