Good for you, but I'm a little confused. So the original Lev will have its HS2 character cards imported into Blender for graphic and animation rendering while LevO will have everything built from scratch in Blender?
If that's the case, won't it make more sense to gradually replace the character models of the original Lev with similarly looking Blender ones and then merge them together?
I don't really understand what's the point of keeping two separate games and workflow here. Like a commentor earlier said, Blender can do anything and largely mimic HS2 style as well, so you can have just one product that works for both Steam and Patreon.
