Simplify collision mesh of road-like system?

Question

Given a tile-based road or sidewalk system in Unity in 3d like shown, I\'m getting mini-bumps of rigidbodies moving over their seams (even for same vertical position & s

You are looking for something called a Composite Collider. 2D Tilemaps even have a checkbox for "Used by Composite". if you attached a Composite Collider 2D component to your tilemap object and tick "used by composite", it will combine all of the colliders into one large collider.

That being said, it looks like you're spawning pieces of road onto the grid using prefabs, and not building your map using the tilemap. You can still use a composite collider for a bunch of different GameObjects by ticking "Used by composite" on the collider, but it is a bit more involved than simply ticking a button on one component, as you will have to configure all of your gameobjects. If you can simplify down to using a tilemap for your roads, it should be much simpler.
