Create tabletop, terraform style for AR game ?

Hi!
I'm looking for help on generating small terrain for a scene in Unity.
I want to create a style tabletop scene for a game in AR using Unity 's Terrain tools

See pictures of what I mean.

Set a height to all terrain to generate a sort of cube or other shape and place on a flat surface


Is there any technique, tool or plugin to be able to make this effect on the terrain in Unity?

Thanks!
Regards

 

Yes, Unity's terrain tools can do this fine. What's the difficulty?

 

Thank you for answering.
Can you help me create this?
Not if you understand me what I want to get
When you create a terrain in unity, it is a deformed plane (see the first image a.png)
And I want it to be massive, like it's a real miniature model.
It's as if the terrain was on a cube or anoher shape (se other images)

 

Ah, I see! So the difficulty is the "sides" of the terrain, from the actual terrain level down to whatever you define as the tabletop.

I think to do that, you would need to generate a procedural mesh. Use Terrain.SampleHeight to find the height along the edge.

An alternative (which is probably what the games you're looking at did) is to ignore Unity's terrain feature, and just model the whole thing in your favorite 3D modeling program.
