Apply texture to text in Illustrator without losing quality

I am trying to apply a texture to a heading of text. I've figured out how to do that using a clipping mask. But I also want to apply an effect to the text after applying the texture. I've done this using the 3D>Rotate effect. However once I do this the texture within the text becomes pix-elated, not having the good quality it had before applying the effect. How can I use the effect I want without losing the quality of the texture?
