2005 Spring ->3D Computer Modeling ->Galleries ->David McSween David McSween   Final Scene   Found   Inspiration Terminator 2 was the first R-rated movie I was allowed to see. Ever since then, I thought the terminator endoskeleton was one of the coolest robot designs I'd ever seen. Since I had fun on the group project building a fairly simplistic robot, I decided to challenge myself by trying to recreate a terminator. The scene is just a typical post-apocalypse vision after the machines take over, the viewer in the place of someone being found hiding by a terminator.

The rest of the modelling I was able to do mostly by using basic shapes and carving them with boolean, occasionally having to move some points around. I probably spent a quarter of my time checking reference pictures during the modelling process. Getting a decent steel texture for the terminator was a challenge. UV mapping was too hard, so I scrapped that idea. Using a steel texture I made looked too plain. In the end, I layered some procedurals to make sure the surface didn't look overly uniform, and messed around for quite awhile with surface settings to get the right sort of shine. It still isn't perfect, and even slightly different lighting variations seem to make or break how well the settings work. The glowing eyes were important for the look, and I just added the glow in with an airbrush in photoshop afterwards instead of spending an enormous amount of time I heard it can take to enable glowing effects in lightwave. The last problem was that the textures looked better with anti-aliasing off, but of course, that gave me jagged edges. With anti-aliasing on, the terminator looked completely smooth. Basically, it would hide all the time I had spent trying to get a decent looking surface. I compromised and put the enhanced high AA render over a non-AA render at about half opacity. Enough to smooth out some flaws, but not hide the texture.
