Claim:
1. A method of using a texture in a graphics processing system in which textures to be used by the graphics processing system can be stored externally to the graphics processing system and pages of the textures then loaded into a local memory of the graphics processing system for use by the graphics processing system to generate texturing result data, the method comprising: storing by processing circuitry respective page table entries in a page table for respective pages of a graphics texture for use by the graphics processing system to generate texturing result data that have been loaded into a local memory of the graphics processing system; storing by the processing circuitry in the respective page table entries for respective pages of the graphics texture that have been loaded into the local memory of the graphics processing system for use by the graphics processing system, respective fade factor values, wherein the respective texture pages comprise respective texture data for generating texturing result data, the respective fade factor values are settable by an application that uses the texture, and each fade factor value controls the contribution that texture data from the texture page for which the fade factor value is stored makes to any texturing result data that is generated by the graphics processing system using the texture data of the texture page for which the fade factor value is stored; and generating texturing result data by a graphics processing pipeline of the graphics processing system using texture data from a texture page that has stored fade factor value, including controlling the contribution of texture data from that texture page to the generated texturing result data in accordance with the fade factor value stored in the page table entry for that texture page.
