How can I create a hill on a terrain or plane in c#?

Hi,

after 4 hours without success, I decided to ask it here.

I'm trying to create a simple hill.

I saw this post here:

Image from the post:


I can't create only one simple hill.

Can somebody give an example, please. Thanks.

 

Use the raise/lower terrain and put the brush size to 100. And the capacity to say 55 and then use the fourth big circle left click about 5 times maximum and should look like a giant pancake. Then hold shift and go lower all around the edges of the giant pancake with the small first circle and the giant pancake should form a hill but probably not as pointy as that image above. Or I think the hill you want which is the second type of hill option would be to use raise/lower terrain and put brush size to 100 and capacity to say 15 then use the first small circle and hold left click and kinda go around barely in a circle and should create that image above.
