This project was at first a training for me on cloud to get better with non-simulated volumes on Houdini, it quickly transformed into something bigger when i decided to add a ship ( which was a 2D doodle but became a fully detailed 3d model instead). With this goal in mind i created a tool to procedurally generate cloud from simple shapes to keep an artistic control over my composition, as well as a pipe generator to help me create the engine of the ship (it'll get their own post enventually).
Final result
The ship model and shading
