I noticed that the transparency map was plugged into 2 settings: Transparency and Transparency_Edge.  However, the Transparency_Edge was not active (0 Value); that did not make sense.  I also had an issue with the Bump_Map plugged into the Gradient_Bump.  In my Material Room setup, I created and introduced a Displacement Map, moved the Bump_Map plugin to Bump, activated Transparency_Edge, and also plugged Transparency_Map into Transparency_Falloff.  The Diffuse_Value was reduced to 0.8, and my Texture Filtering was left at Quality.  This is the same as ticking on Texture Filtering in the render (I am doing this in Poser 8). Note the image above.
