I FIGURED IT OUT!!!
If you look on the page that resolved your last post you can see that you can use Region3s to generate terrain!
EX:

    local region = Region3.new(Vector3.new(0,0,-3), Vector3.new(4,4,4))
    region = region:ExpandToGrid(4)
    game.Workspace.Terrain:FillRegion(region, 4, Enum.Material.Slate)

Result:
YAY

(The function is Terrain:FillRegion)

Raycast down on the terrain and put the object where the raycast hits the terrain

I was trying to do this earlier. It is a nightmare because you have to cast in a lot of places and it causes a lot of lag.

Expanding upon what @heII_ish said I think you should measure the x and z axis and reference them in a script, then you can use a math.random function to choose a random number between the length of the x axis and do the same for the z. Next, you raycast from that point by using workspace:Raycast (I don’t know how to use the old one) you check where the ray hit and place a tree there!
