I cannot figure out how the light probes are working.
I’ve added component > miscellaneous > Light Probe Group to a new gameobject. When I press Add Probe, nothing happens. I’ve tried searching around the scene to see if anything was created, but I couldn’t find anything.
What are factors that change the availability of light probes in my scene?
I realize this is an old post but I was having the same problem and did not see any newer instances of the question. I was able to fix the problem by creating a new Scene tab and deleting the old one. The little Lightmap Display window wasn’t showing up for me either, so I was not even able to toggle the View Probes checkbox. Both problems were resolved after switching to the new Scene tab. You may have already solved your problem, but if anyone else experiences this hopefully this will help.
If the issue is “Light probe group not visible” then try adjusting the 3D icons’ slider, available under the “Gizmos” drop down list in the scene window.
It worked for me and the light probes are visible now.
(I know this is too late, yet I hope it helps someone in search )
