Seams and weird shadows in Modular Meshes

Hi, I have some issues with shadows and seams between modular meshes. I’ve gone through some answers and adjusted my UV’s to have at least 2px spacing between each UV island and that the UV’s are snapped on grid.

These screenshots are with
Static lighting level 1.0
Indirect lighting quality 1.0
Indirect lighting smoothness 1.0

Adjusting these to
Static lighting level 1.0
Indirect lighting quality 2.0
Indirect lighting smoothness 0.6

Makes the shadows more wavy and the seams to be much less but I cannot eliminate them and the trade-off for bad shadows for less seams seems to be a bad way to proceed.

Decreasing the Static lighting level to 0.1 makes it even worse

Lightmap resolution for the meshes are 64, increasing them also gives me the same result

Lighting issue -> shadow issue on edge of meshes

Sorry for another light issue topic 🙁 The situation: I have 2 copies of a mesh(a wall). I have assigned the same material to them. The lightmap resolution is the default value: 64. After building the lightmap on production quality I see a line(I...

There are some other threads which states that it is not possible because each mesh is rendered on a different thread causing the seams.

How do I fix these issues ?
