Question by ryf9059 · May 07, 2015 at 11:57 AM · unity 5lightinglightmaphierarchylight probes

Light probe still exists in the scene after being deleted, cannot be selected.

I'm trying to create a Unity scene where I tackled with the light probe group for a bit. Later I decided not to use it and deleted it from the hierarchy. However I find out that the association of object with the light probe still exists and every time a bake a scene it takes forever because all the object that uses light probe. In fact I can still see the light probe in the scene but I was not able to select it. Also searching the the hierarchy yield no results since I already deleted it. But it is still there and is taking a lot of resources. This is very annoying. Anyone have experience and can help? Thanks.

Here are the screenshots of the problem I described.

Have you tried copying the object associated with the light probe, delete the old copy, and see if it is still there?

@joshua.lyness The is long after I have deleted the light probe, if I were to create a new object that object still has the yellow line indicating association. That said, even I create an object right now, there is still going to be an association with the long deleted probe which I can do nothing about.

Hi, I had the same problem, maybe you could file a bug if you have a simple case to reproduce it and send it with the bug report. I think clearing the lighting baked data fixed it (the menu integrated in the "build" button of the lighting window, you have to uncheck "continuous build" first)

I have the same problem.

I deleted everything in the hierarchy.

Still the light probes show in my empty scene.

Even clearing GI cache / disabling lighting doesn't solve the problem.

Check every Object's Mesh Renderer for 'Use Light Probes'.

I found that because one of my objects had 'Use Light Probes' ticked in the inspector, that the Light Probes in the scene couldn't be found / deleted. Once I had removed the tick, re-baking the lighting cleared the probes.

LightmapSettings.lightProbes = null;
