When light baking this tower i have im getting some weird artifacts. There are lines that i cant get rid of. Its being caused by the shadows as when i deactivate them the artifacts go away. Also when i increse the resolution in the bake settings more lines appear??? I also generated lightmap uvs on import.
Hmm, are you using interpolation points in lightmaps parameters?, may be that…
Can we get a clearer screenshot of the model and the resulting lightmap maybe?
Solved it. I changed the bias in the beast lightmap file to .001
