Work-in-progress: started this engine about three days ago. Blocked out forms first (dark grey surfaces) and then recently started doing some initial detailing. Mix of subd and poly surfaces. Getting my old modelling speed back, thanks to Pearl Jam and Audioslave. Below is the reference engine: Isuzu C240, an engine type commonly used by jeepneys throughout the Philippines.
I don’t think I’ll be hitting this engine with any sort of obsessive detail since it will be significantly obscured by its placement in the robot.
