I made this 3D Model of a Sno-Cat recently for comic book artist Dylan Teague
Dylan is currently illustrating a comic and needed some good reference for a Sno-Cat vehicle, having searched online Dylan asked me if I could make him a 3D model so he could import it into Google Sketch-Up so he could then use it to help him with the specific angles he needed for the strip.
The model is based on a number of Sno-Cat references that both Dylan and me found in an online search, and the model is a bit of a hybrid of those. It didn't need texturing at all so it made the job quicker. I've seen some of the panels that this is getting used in and it looks cool, and I'm sure Dylan will be posting pages from the comic on his site soon.
