Lightmap error

This is probably very simple, as I’m still learning lightmaps and how they. I have a modular trim piece that has some sort of shading error when I line them all up together. I’m pretty sure it’s the lightmap because when I change the resolution the error sharpens up.

If anyone could point me in the right direction, I’d really appreciate the help.

I fixed the issue by manually creating a lightmap, although the resolution of my shadows isn’t as nice now. I might just settle for this because the piece will be high up and hard to see. Wish I knew what was making the blotchy shadows though.

Solved, I read the documentation
