Transparencies/Alphas on OBJ textures?

  • I hope I didn't miss this somewhere, but does CSP support such rendering? Say I have an object with transparencies in the PNG texture, is there something wrong with say, MTL file? I'd find a feature such as this greatly helpful in the way I model hair. An example file would be - this should be an invisible cube with the glyphs stamped on it. Am I doing something wrong or just expecting too much?
