Lighting issue

I have imported two static meshes and put them side by side. However, when I build the lighting, they have extremely different lighting. I have ensured that their lightmaps are the same resolution and that there are no errors pertaining to those meshes. I have a picture attached. Thanks in advance for any help.

Hi!

Defaults, UE4 builds the lighting with low quality, and you need adjust parameters of the lighting for highest quality. I recommended this thread:
