Anyone know why I am getting these artifacts? For reference this on built production quality lighting. The vast majority of the lights in this scene are spot lights. There is a skylight in the scene as well.

Need higher lightmap resolution, probably a lot higher. Use the lightmap density viewer as your guide, aim for at least green
