@MacGruber is correct about VaM being based on G2 Models, but conversion, while a bit of a hassle sometimes, is possible. If you'd like to give it a shot DM me and we can chat about doing some conversion work. I'm willing to take a stab at it.
I'm running into the same problem. I'm judging what I make next basically on how quickly things get to 1k downloads as that's the only feedback that I have access to. Would be cool if there was a way in game to leave a comment or something.
