What I do in these cases is described here:
http://mathematica.stackexchange.com/a/1551/245
Before making any plots, execute this command:
Map[SetOptions[#,
Prolog -> {{EdgeForm[], Texture[{{{0, 0, 0, 0}}}],
Polygon[#, VertexTextureCoordinates -> #] &[{{0, 0}, {1,
0}, {1, 1}}]}}] &, {Graphics3D, ContourPlot3D,
ListContourPlot3D, ListPlot3D, Plot3D, ListSurfacePlot3D,
ListVectorPlot3D, ParametricPlot3D, RegionPlot3D, RevolutionPlot3D,
SphericalPlot3D, VectorPlot3D}];
