Question Baked lighting weird behavior, please help :)

Hi guys, I have baked some lighting and one model is not behaving as expected. Its a model of some molecule and its placed on a wall, they both use same material but they don't get baked the same. I will attach screenshot of the model and the lighting settings.

 

Thank you for the response! I didn't tick the "Generate Lightmap UVs" and I also found out that the lightmap resolution was probably low. By the way, really nice guide you made there, found it after posting this question though, my bad
