So in this file the object will not receive light from this emission plane.
I have "“surface” as emission plane and then I have a image to give character like in world hdr setup. I have a file that this does work on. But on this one as you can see its prejudiced against my emission plane. So far have not witnessed this.

Now in this file I have 2 mysteries. THe plane on the bottom dissapears when I go into render mode. ANd again on a different computer this emission plane will not light up this cube as the regular lamp will. I can not even guess why this object will not receive light would
this is 2.81a
It was because I was in NOT in cycles. SO apparently EvEE does not support emission material?
Still do not know why this bottom plane on the emissionproblem.blend hides when I go into render mode
So when things go wrong in blender I need a diagnostics checklist to go by. There are all these requirements to be in place for things to work.
