Light Probes not Tetrahedralizing when loading scene in editor

This is strange because it doesn't affect all of my scenes, but several of them keep the previous scene's tetrahedralizing (the pink lines) instead of showing its own. When I click the "Edit Probes" button, the pink lines suddenly change to where they're supposed to be. However, I'm also having this issue at runtime.

Even at runtime, when I call LightProbes.Tetrahedralize() after loading or unloading a scene, with certain scenes, the pink lines still look like they're from the previous scene instead of using the new scene's light probes for the pink lines.

Example... I load this scene and see the pink lines where they're expected.


Then I load this scene, and despite seeing all of the light probes in this scene, the pink lines are still where they were for the previous scene.


Finally, I click the "Edit Light Probes" button, and suddenly the pink lines appear as expected in this scene.

 

It's very important to note that this doesn't happen on every scene. Some scenes work as expected. I noticed this because at runtime I'm not getting the lighting I'm expecting, depending on the order of scene loading and unloading.

Also, can you verify if I am doing this the way Unity intends? Here is a use case:
1. Load main scene (no probes)
2. Additively load Scene A (with probes) and tetrahedralize. I'm expecting only Scene A's probes to work.
3. Set the Scene A's root GameObject inactive because I temporarily don't need it. Tetrahedralize, I'm expecting no probes to work.
4. Additively load Scene B (with probes) and tetrahedralize. I'm expecting only Scene B's probes to work.
5. Unload Scene B and tetrahedralize. I'm expecting no probes to work.
6. Activate Scene A's root GameObject and tetrahedralize. I'm expecting only Scene A's probes to work.

I can file a bug and reference this thread, but I don't know if I can provide a project to reproduce it. My project is way to big to include on a bug report.

 

What seems to be happening is:
1. Load main scene (no probes)
2. Additively load Scene A (with probes) and tetrahedralize. I'm expecting only Scene A's probes to work.
3. Set the Scene A's root GameObject inactive because I temporarily don't need it. Tetrahedralize, but despite being inactive, are still included in the probe data.
4. Additively load Scene B (with probes) and tetrahedralize. I'm expecting only Scene B's probes to work, but Scene A is still working too.
5. Unload Scene B and tetrahedralize. I'm expecting no probes to work, but Scene A is still working too.
6. Activate Scene A's root GameObject and tetrahedralize. I'm expecting only Scene A's probes to work. This is indeed the case.

Was there a change between Unity 2018 and 2020 in that all additively-loaded scene's light probes are now included instead of only the most recently loaded scene's light probes? That's what I have gathered from stuff I've read, and it seems to be the case, but what is throwing me off here is that inactive light probes are still being included in the Tetrahedalize() call.

 

Hey @thefranke can you confirm or deny what I wrote above? Are inactive light probes supposed to be included in Tetrahedralize()?

 

Thanks for the reply. This is unexpected, but it's good to have my strange behavior confirmed. Clearly, there is still a lot of room for improvement in this area. Are there still plans to make this more flexible and controllable?

 

Hello so what basically we have to do to reload scene in editor, for now we have to always load scenes i proper order even in editor what is annoying, Is there any tool, or buton to refresh lightprobes in editor too? or we shoudl use the same method as in runtime?
