(IN-2417) Progressive GPU lightmapper cannot bake a number of light probes

Hi, I found that GPU lightmapper cannot correctly bake light probes when the scene has a number of light probes. If the scene has small number of light probes, it is baked correctly.

CPU lightmapper does not have this issue, it bakes correctly regardless of count of light probes.

Reproducible project is reported as IN-2417.

Have the customer QA responded to you about this issue yet? It hasn’t reached our team still.

@kristijonas_unity Hi. I received response like this:

Also I found that it still occurred in Unity 2022.2.0a16.

@kristijonas_unity Hi. Any progress for this issue?

Hey, sorry for the lack of updates. We have finally received the issue. Seems like it only affects light probe visualization and not the baked probe output. Regardless, we will fix it in the upcoming sprints.

Hi. But I found that it not only affect visualization, but also actual lightprobes are incorrectly baked. Objects in Scene view does not affect from lightprobes correctly.

Okay then this is a more serious issue than our customer QA had previously thought. Thanks for letting us know.

Hello @Kichang-Kim ! I was able to reproduce the visualization issue, but I cannot reproduce the difference in LightProbe bake output that you are experiencing. Can you attach a reproduction project and comparison images for us?

@giorgos_unity Hi. I reported additional project and attached comparison screenshot. Report number is IN-9852.

Thanks! I’ll take a look and I’ll get back to you.
