Baking lighting in unity looks terrible

My lighting settings are attached is there any reasons as to why this is happening?

check your lightmap uvs. If the plane is too big, it's a normal result for 1024x1024 lightmap

Thanks, I’ll try that when I get home

Max lightmap size will not directly affect much lightmap space you'll have
When reaching that limit, another lightmap is created so it affects how many lightmaps there will be versus how big

But with very large lightmapped surfaces it can't split the surface into two lightmaps without a seam, so it's forced to shrink it instead

That said lightmaps are very inaccurate for direct shadows, and very inefficient for surfaces where the required detail varies a lot

If you have a huge plane with almost no sharp shadows on it besides one, the resolution of the plane's whole lightmap will need to be big to capture just that one shadow accurately
