I’m new to Blender and just started 2 days ago. I watched YT and get me started, but I can’t get rendering to work properly. All verticals objects are dark and top surfaces have good. I’m using Light/Sun since I just need my object to be lit. Not fancy but that’s what I need for now.

What am I doing wrong? What setting needs to be changed?

  • $\begingroup$ @moonboots Why? The screenshot shows he is using Eevee, the sun points straight down and even Shadow is disabled. And from this premise, L0Lock gave a detailed explanation of what he could do. $\endgroup$ Sep 14 at 7:58

Your Sun light is perfectly pointing down. And I guess you are rendering with Eevee or Workbench since there isn't any visible Global Illumination. So you need to rotate it a bit if you want your walls to receive any lighting.

A sun light provides light of constant intensity emitted in a single direction from infinitely far away. It can be very handy for a uniform clear daylight open-space illumination. In the 3D Viewport, the sun light is represented by an encircled black dot with rays emitting from it, plus a dashed line indicating the direction of the light.


This direction can be changed by rotating the sun light, like any other object, but because the light is emitted from a location considered infinitely far away, the location of a sun light does not affect the rendered result.

If you use indeed Eevee, you might also want to check a few things:

  • Enable contact shadows in your sun light settings: enter image description here
  • Enable Ambient Occlusion: enter image description here
  • Enable Screenspace Reflections: enter image description here
  • Add an object Light Probe > Irradiance volume, make its spheres spread across your scene, and bake Indirect Lighting: enter image description here
  • $\begingroup$ Yes, he uses Eevee. The (disabled) Shadow option on the sun lamp is not available in Cycles or Workbench. So first of all if he enabled it this would already be a step in the right direction. $\endgroup$ Sep 14 at 8:01
