I experienced this weird lightmapping bug in my game that causes some models to have glowing artifacts on their surface. These artifacts "move" around, when I edit the UVs of the model in Blender, so I assume that it has something to do with them. I took a few screenshots to hopefully clarify the issue.

• Engine used: Unity 2019.1.4f1
• 3D Software: Blender 2.79b

If you need any other screenshots or something, let me know. Thank you in advance!
