I mean't just the weapons, not the model taken directly from the bricks.
I don't think you know much about this.
The brick is a blockhead holding a gun,from what i understand.
You want me to edit out he gun,turn it into a animated weapon.
And it will be the happy ending.
But sadly you cannot import models from a .bls file from my knowledge,you can ask other brick makers via PM but i'm pretty sure you cant do that.
