1. A method of rendering a scene formed by primitives in a graphics processing system, the method comprising:
retrieving the stored fragment shading rate data and data identifying a primitive, the fragment shading rate data representing a preliminary combined fragment shading rate value for the primitive;
obtaining an attachment specifying one or more attachment fragment shading rate values; and
for a primitive fragment derived from the primitive, combining the preliminary combined fragment shading rate value for the primitive from which the primitive fragment is derived with an attachment fragment shading rate value from the attachment to produce a resolved combined fragment shading rate value for the fragment.
