I did this a few years ago for a modular trench-based game. I made instance-copies of all the sections, overlaid them, added an Edit Normals modifier to all of them, marquee-selected each vertex, Average button. Repeat for each vert along the seam. This ensures every vertex along the shared seam, for every model, has the…
