X-Ray images can be interesting. They are both clean and technical in aesthetic and the effect can be easily reproached in a 3D render. As a demonstration, The Pixel Lab’s Joren Kandel walks through creating a see-through multi-colored X-Ray like the kind you would get from an airport scanner.
Joren uses Cinema 4D and Octane to get the X-Ray look, and shows some opacity tricks using the Octane Dirt Shader to get the “center-edge” look to the XRay render. This will make the edges look more opaque than the center faces of the model, using the model’s surface normals.
Of course you can get all of the models used in the tutorial, including the free weapon models, if you would like to follow along.
