Vertical terrain features

Hi all,

So if i use a regular terrain object i can do almost everything, but i'm wondering how do i deal with cases where i have a directly vertical cut off. Say I have a terrain, and i want to 'cut out' a square to place a building halfway into the terrain.

Is it always handled with covering up with models or do i create a second terrain to handle this or whats the best way?

Can i just 'hide' a terrain tile or gradient - eg. dont draw the terrain between vertex 5 and 6?

Thanks,
Primoz

 

Yes, it's usually handled with cover geometry. And yes you can paint holes https://docs.unity3d.com/Manual/terrain-PaintHoles.html

 

Nice question. Yes, it seems like if you need cliffs or other vertical structures, it may need to use meshes to cover these areas, i.e. I quite like images in this thread which illustrates how mesh is fitted with terrain:

Holes alone won't do much, it's all about the way how you craft that mesh and how you make it to connect nicely with terrain in places where you need vertical structures.

I am still wondering if there might be nice ways of doing this fully procedurally
