This is a private project that I made in the past three months. Maybe it´s the wrong signal to build a bike that runs on coal instead of green hydrogen. But I can tell you that it´s a lot of fun to model, texture and light such a monster. 

After doodling around to visualize my ideas, I started composing the first very simple bike in Cinema 4D. It´s about playing with primitive parts and proportions, the cubes and cylinders will become functional units later in the designing process. 

The model of the biker I did not produce myself. It has good textures, but was unrigged, so I had it rigged in Adobe´s client mixamo. Also, I needed a good location. I decided to let the bike run through a tunnel, which on one hand gives me a not too complex, uniform background and on the other hand brings some audibility into the image, because you can allmost hear the steam monster shuffle through the short tube. 

After editing all parts in Cinema 4D´s UV edit I started texturing in Adobe Substance Painter. It´s the perfect tool to create worn, rusty metal textures and it´s fun to use once you got the hang of it. Then I transformed all substance textures to Maxon´s renderer redshift, who can deal with enormous amounts of texture maps. 

The first prototype in the virtual studio. Some parts still have to be changed, but it gives a first impression of what the surfaces look like.  

Cinema 4D has an inbuilt pyro engine, that creates very realistic fire and smoke simulations. Anyway I decided not to use it and paint the smoke instead. But I happily used redshifts very realistic motion blur in order to speed up the whole image.
