super noob question here.

I have created a very simple scene with just a cone, a light and a camera. The cone has a default white material and I selected "shade smooth" for it.

The light is the default light and is placed at the bottom of the cone and a bit in front and to the side of it.

I am not trained as an artist, so I don't have more than a vague idea about how the end result should be. In my understanding the light on the cone should have at least a more round shape.

Obviously there is something I am missing here. The default settings produce the results below.

I am using blender 2.90.1 on a Mac.

Is there anyone who knows what my problem might be and how to solve it?

Please let me know if there is any more info about the scene that I need to write in order to get help.

Thanks :-)

When I render the scene with eevee I get weird artefacts:This is what I get with eevee

When I render it with cycles it is a bit better but still weird: This is what I get with cycles

  • $\begingroup$ So far I know is, shadow could be blocky even it has shaded smooth. Maybe try add a subsurf, although it will mess the cone? I’m not sure about it $\endgroup$ Nov 19 '20 at 12:00
  • $\begingroup$ I did some testing, and cones (even cylinder with the top scaled to a small value) don't play nice with shade smooth. I recommend more vertices or holding edges and subdivision. Refer to this question: blender.stackexchange.com/questions/194494/smooth-shade-a-cone $\endgroup$ Nov 20 '20 at 18:42
