The Star Wars: The Old Republic site has been updated with a fascinating look at the creative process behind the Flesh Raiders. The inside look shows how concept art is created from the initial idea through the modeling process. It's a great read with some terrific looking screenshots.
After gathering and studying art work and other assets related to the Flesh Raider, I started off with a base which is a rough body sketch similar to an existing one in the game. At this point I was not exactly sure how far we wanted to stray from the original design, so in terms of the head and protrusions on the body I threw out some different ideas on what could be done. I tried not to spend too much time on the base, but wanted to give enough detail so there was a clear idea of what I have in mind. I even threw in a crazy wacky one to see if the team wanted something completely that deviated from the current Flesh Raider model.
