I love the way these assets look and the price point is fantastic, however if you plan on using them with an engine that supports snapping, you’re in for a bad time. A lot of the sizes are not uniform (4.11m, 4.10m, 3.75m) and even some things that seem to snap together properly (like walls) you’re going to have minute little gaps between them.
Lastly, some objects, like the tiled floor have holes in the model, between the individual tiles, that show the endless void beneath them (or lights from elsewhere, depending on what you’re doing).

While these issues are not a serious problem if you plan on hand-crafting your dungeon, the current project I’m on needs to treat these objects like tiles for algorithmic generation, which is unfortunate.
