It's unnecessary though, and it'll be insanely complicated to actually pull off
Then why not create the illusion of building your own avatar?
limit the bricks to each individual part and limit the decals and you basically have the original blockland avatar system but it looks
like it's made of bricks.
Besides, Insanely complicated sounds like a challenge.
its not cause your avatar would break upon joining other servers without the brickpacks
also people would basically build snakees which is dumb.
Well you could limit it so it would be default bricks only.
Also you could limit the height, and even the brick selection if you so desire.
