TileMap & Vertex Snapping

I’m trying to some 3D room shapes with TileMap for practice. I use multiple Tilemap renderers in different angles and put together rooms. I noticed that Tilemap renderers do not accept vertex snapping so I have to link each wall portion by eyeballing it, which can be tedious especially in 3D space.

Does anyone have any shortcuts to allow vertex snapping in Tilemap ? It would be a useful feature.

I’m not sure I understand completely. Do you mean you are using a Tilemap for the floor, and a Tilemap for each wall, and they are perpendicular to each other? Could you attach a script to the Tilemap gameobject that snaps the transform position to a certain grid?
