What You'll Be Creating

In this tutorial series, I’ll show you how to create a Fuel Pump in Maya. I'll start with basic low poly modeling techniques and then cover the highly detailed modeling, texturing and baking of this object in later parts.

This series is a follow up tutorial of Create a Game Ready Fire Extinguisher with 3D Studio Max series, but in Maya

1. Creating the Base Plate of Fuel Pump
