Baking lights in unity with Progressive GPU looks bad

I’m trying to bake lighting for static interior scenes in unity, the camera is just going to move around, so all lights will be static. These are the results after using Enlighten, Progressive CPU, and Progressive GPU as the lightmapper:

Enlighten:

2000×964 191 KB

Progressive CPU:

2000×967 180 KB

Progressive GPU

I don’t know the reason why Enlighten makes the lights brighter but my biggest concern is why the Progressive GPU options look so bad. Since this one is the one that takes the least amount of time and I’ll be baking several of these scenes constantly, this is the one I’d need to use.

I’m using the default settings:

I haven’t found any help online regarding this issue yet, please help, and thank you for your help

I mean CPU also has these artifacts just less than GPU for some reason. Those look like rejected texels to me, which means you have open backfaces. Try reading this: Lightmapping Troubleshooting Guide

Thank you so much!
Activating the “Double Sided Global Illumination” feature in my model solved the issue.
