This is still not implemented after being tracked for 6 years.

Opened up another one here: https://feedback.vrchat.com/feature-requests/p/exposed-lightmap-settings-to-udon-for-swapping-lightmaps-at-runtime

Sometimes you have to remind the developers to finally update U#. its actually very sad that this is being tracked since 6 years.

Trying to create a bunch of rooms that are playerobjects but cant update lightmap data to match the baked original. I assume LightmapSettings would allow that based on the documentation, but sigh

5 years passed....

Bump for this. Multi-lightmap support opens up a lot of options for making high fidelity maps with day/night cycles or even toggleable indoor lighting and it's a shame this isn't already here.

I'd love to be able to swap light probes at runtime with this 🌸 we have very few ways to light avatars in VRChat without resorting to projectors 💖 it's important

Im so gonna need this.

cause Im planning to have multiple lightmaps for my world, so it would be nice if I can use "LightmapSettings.lightmaps" command to switch the lightmap according to the situation

I definitely support this, in particular exposing lightmap settings for probe data.

This would be a huge boon for a few things - but for our use, it would allow us to use bakery, and also still have RTGI that can illuminate avatars for select small areas of the world. EDIT: I now realize that may not be as feasible as I expected.
