Tessellation static lighting seams

Hello!

I’ve stumbled upon a problem with tessellation and static lighting.

As you can see below, there is an ugly seam between my cave floor and walls.

The same thing occurs between the walls and ceiling.

As I found out, one way to fix it is to have a solid mesh with no geometry or UV cuts. But at this point, I can’t afford to re-do my cave walls/floor/ceiling. That would practically mean starting the whole project from scratch.

If I disable tessellation, then the whole thing is seamless. But naturally, surfaces do not look nearly as good w/o tessellation.

Is there any way to mitigate this problem somehow?
