3D Tile Map functionality

Hello.

I am trying to find a built-in functionality in Unity engine for easy creation of 3D tile maps, but it looks like there are none available. Correct me if I am wrong. All the 3D tile map fucntionality which I find is a paid add-on. There are many similar paid add-ons which do similar things and compete with each other. I do not want to do research which of them is better and which has bugs, I just want to use the base free version of Unity editor to create game world as simple as in the editor of OpenTTD game, but in isometric 3D world.

By the way, I have found this functionality in Godot 4 GridMap component. I do not know anything about Godot yet, but it looks like in that editor 3D tile maps are a built-in free functionality.

Am I missing something ? Does the standard Unity editor provide 3D tile map component ?

P. S.

I have found a video showing some basic 3D tile maps in Unity – https://www.youtube.com/watch?v=ulFc6p3hQzQ – but it says that a lot of functionality which is available for 2D tile maps is not available for 3D tile maps. This video is 3 years old now. Did anything change in this field since that time ?

Thank you.
