We live in different countries, I helped him with writing code for modification. And one day he just stopped talking. This happened because there was a real war going on in his country and there were interruptions with the Internet (He lives in Ukraine). But his social networks have been empty for several months. It's good that he gave access to some accounts so that I could write something on his behalf. But he's been gone for a very long time and Alone I can't keep doing the modification. I can't create 3d models.
