I apologise for the English. Prompt, whether there is an arrangement possibility mesh a little below level terrain, I looked in have found wiki-nothing. That is it is standard obj puts as drawing 1, whether there is a possibility to put it as drawing 2

use the mesh editor.
load your mesh and move it down a bit

you dont need to modify it in ME, you can just move it downwards with Ctrl+RMB (the shortcut is in the docs)

Thanks
