BioWare Technical Artist Ben Cloward, posted a Developer Update intending to inform the community at large about technical changes coming to Star Wars: The Old Republic in Game Update 1.5.
Quote from Ben Cloward
As a tech artist, I create tools to help the artists get their work into the game, and I work with the programmers to make the game run more efficiently. One of my favorite things to do is write shaders. Shaders are small programs that run on the graphics chip that describe the appearance of surfaces. For example, shaders define if an object looks shiny or dull, reflective or matte, and they also help us define the visual style of the game in terms of how lighting works.
While it may not be the most exciting Developer Update, it's good to see the team continuing to optimize and update the engine.
