This is an attempt to create a metal/steel-like material... and in order to add a bit more appeal on top, I also tried to mimic a not yet fully polished 'function surface/coating'. The model is a low-poly mesh from Sketchfab https://lnkd.in/e2xCdwJh Yes, the mesh is a bit odd... the wall-thickness between the cylinders is too thin to make sense in the real world... and it is missing coolant passages. #vtk #shader #pbr #rendering
