Question HDRP Lightmap Relocation?

    I'm developing a game with a procedurally generated map. The easiest way to imagine it is as a randomly created dungeon. All gameplay is confined to rooms and corridors. I want to be able to create rooms as prefabs and spawn/despawn them as needed. However, because lightmaps are tied to the specific location of objects in a scene, baked lighting is a problem for this design.

    I looked into lightmap relocation two years ago. At that time, there was no high level support for dynamically revising lightmaps built into Unity, although I did find a blog post and some videos about a game where they coded a lightmap relocation system. I realize that lightmaps can certainly be manipulated at a low level via existing APIs. What I'm after is something simple to use.

    What I want know...
    • Is high level lightmap relocation support built into Unity now? Like I said, I looked into this two years ago. Things may have changed.
    • If not, are there any assets for lightmap relocation? I'm a one-man-show and don't have time to develop a complex system like this.
