Redwood - this Blended Background should be used with my Redwood wide cover spline or these trees which make up the spline: Douglas_fir_14, Grand_Fir_10, Grand_Fir_12, Redwood_50, Tanoak, 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.
