I have an object that was imported as a vrml, and I applied a color and texture to it and it seems to be fine until I render it. The color and texture is present, but on half of the object, the objects mesh (Quads and Tris) show through the texture. Is there a button that I need to turn on?
Maybe try to select the object and go to F9 and then under link and materials there is a set smooth button on the lower right side of that section. try that and then render.
