yeah, so i’m new to blender and for my first project i wanted to model a Chevy Camaro, so i started it, and then i got to a point where i thought i should render it to see how it was going so far, and the results…
It looks like your entire model is a single, huge polygon. Split it all into quads (squares), and change the shading mode to smoothed faces. After that, put on a subsurface subdivision modifier and see how that comes out.
