Short description of error
[Please fill out a short description of the error here]
Lights are completely ignored while rendering in EEVEE

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

(Fig 01)
Lights in EEVEE are ignored completely. Emission objects are working normal and illuminating other objects in the scene. Performance > High Quality Render has no effect.

(Fig 02)
If I disconnect Shadow setting in Light settings, it renders the light, but shadows disappear. Emission object still works fine.

(Fig 03)
Same scene rendering in Cycles works fine, lights and shadows.

I have been observing this problem in previous versions of Blender (2.93x) not 2.92 where I am working now due this bug, but today I installed Blender 3.0 loaded factory defaults, didn't install any plug in or anything, just installed Blender 3 and did the experiment right away, and this is the result. EEVEE not rendering any light, not a 10W not a 1000W either.

This is a Blender problem or I'm doing something terribly wrong in some configuration? Thanks for any help, and thanks for Blender.

Hi,

When you say lights are not rendering, do you mean their shadows?

Here's an Eevee render of your file with a few settings changed (ignore the black dots in the screenshot, caused by running in a virtual machine with GPU software rendering)

Settings changed...

  1. Viewport shading > Material Preview mode > enabled Scene Lights and Scene World
  2. Render Properties > Render Engine > Eevee
  3. Select the Area light
  4. Object Data Properties > enable Shadow (shadow settings are only visible when Eevee render engine is enabled)

Hope this helps solve your issue.

Hi David, thanks for taking the time to check on this. The problem was that Blender was rendering the scene like there was no light added in it, like the fig 01:

That happened in v2.93.x and v3.0, not in v2.92, but yesterday, Windows updated the Intel driver and while I was reviewing and trying your solutions, the problem wasn't there. I couldn't reproduce it at all. I think it was the driver. So, thanks for your time anyway.
