Wow, that looks great!
Ah, I just rewatched that scene, now I know what you mean. I thought you meant it was moving in its closed position, but you mean that once the stock is opened the rear moves around quite freely. So does that mean your stock in its opened position will not be able to move from left to right to "simulate" auto aim?
That‘s too bad… I understand to a certain extent, but couldn’t that just as easily happen with .stl files though?
On the plus side, that means my own F44AA CAD project is still on. Can't wait to put my new modelling skills to work, I had to up my CAD game a bit modelling the M240 flamethrower in Fusion.
Cheers!
