A fun project I spent probably way too much time on. It's based on a song I sang growing up.
"There was a peanut sitting on a railroad track and his heart was all a flutter... Train came roarin' round the bend... Choo choo-ed peanut butter!"
I had drawn this image a while back. It just asking for a 3D version.
Clay render (I love the Blender 2.8 veiwport!)
The Peanut was textured in Substance painter.
I had originally wanted it to be raining, so I had made wetness textures that I didn't use.
I only modeled one half of one rail and beam section...
...then mirrored it and duplicated it along a curve for easy positioning in the scene.
I didn't spend much effort on texturing the train, but it got the job done. (Textured procedurally in Blender)
The train model is very low poly. The smoke sim was fun as well!
