Emission maps and sprite atlas issue

I am using the URP. Pictured is a land mine sprite which has an emission map as a secondary texture. In the editor it glows as intended. However, in the game it does not. The mine sprite is part of a texture atlas. My hope was that the emission map would be included in the texture atlas. My guess is that it currently is not and that the editor view is using the individual sprites as they are on disk before packing them. Are there additional steps required to have emission maps in texture atlases? I have seen this glow effect work with sprites using sprite mode multiple, but those appeared to have been sliced manually and were not using Unity's automatic texture atlas feature.

Any ideas, tips, or alternate approaches would be appreciated.

 

@phil_lira Sorry to beg for attention in the matter, Phil. If this is a fringe issue, I’d be interested in hearing what I should be doing instead.
