Changes to Material data causes error in ID decrementing about the_lightmapper HOT 3 CLOSED

Upon further inspection, this error seems to be separate from whatever was preventing the baking from completing properly on certain objects.

Hi, thanks for reporting this bug

Changing materials on already baked materials generally isn't supported, unless you're sure they're finished baking, I've yet to make an event listener for checking edited materials - Similar to other engines (such as UE4), changes generally require re-baking of the light, although it's especially prone to errors when names are changed in the baked state.

The original materials are hidden, but can be restored by searching for .MaterialName_Original (the dot hides the material from the list). The ID decrement error comes and goes, although it usually doesn't cause any significant errors.

In any case, I'll try investigating the issue

Gotcha. I still have no idea what directly caused the baking error though (one of the objects came out flat gray every time I hit bake) - if/when I find out I'll open a new issue for it.
