    Hello,
    In previous iteration of the development of my game, I used the subractive mode for lightmap backing. Now I use Indirect which gives better results. For performances reason, I want to use subtractive on dedicated maps on mobile devices.

    So I have duplicated my PC map and rebaked it using subtractive mode. The result is wrong because my terrain is black. If I create a new map with a new terrain, without the content of my other maps, it's ok, it bakes well. If copy some content from my other maps, the terrain is black.

    Any idea on how to debug that?

    Hey there, a few questions:
    Which version of Unity are you on? And I assume you are using URP?
    Are you using the same lighting settings for both scenes, and which resolution are you using for the lightmaps?

    Some screenshots or a small repro project with the scene causing issues, would be helpful.
