One of the challenges was to ensure that having positioned the legs that the model not only could stand, but was also stable so wouldn’t fall over during a game. I didn’t really want to have to base the model if I could help it. This is so I could use it in various games and not have a grassy scenic base whilst playing Cityfight style games.
Though… of course if you do use a base, you could convert the model to make it look like it was walking rather than standing.
