鵝卵石／泥土斜向回填（已塗裝）

Finally, a clean way to finish off the off-kilter builds. The double-sided texture means I flip them once and they match both my cobblestone and dirt sections, which saves a ton of fiddling. Painted finish is subtle but consistent, and they slot in without any gaps.

The double-sided feature on these backfills is a lifesaver for keeping my dungeon tiles aligned when I use diagonal walls. They fit perfectly with the cobblestone ground cover I already have, and the painted finish matches nicely. My builds look so much cleaner now without those awkward gaps.

The diagonal fill pieces are painted nicely and match the cobblestone ground cover I already had. They’re useful for keeping the grid aligned when you want to lay out a diagonal corridor or alcove. My only small gripe is they’re a bit snug to fit in place at first.
