It's a machine where you can make your own burgers but I need some help with improvements.

1. The salt and pepper shakers suck. can someone help me make a machine where it automatically rotates the shakers and put it on the burger?

2.The physics of the onions, tomatoes and pickles are really, really crap. Please help me make it a bit more realistic.

3.The scene lags like hell on some (my) computers. So Is there maybe a way to make a spawner where you press a button and the burger patty, bun ect. drops, and you can drag it on the burger.

And is there anyway to make the machine kinda automatic.

Please help. This is my third scene and people like it and the previous one. So Please help me make it better cause i'm a n00b

I would like to help you.

The scene lags like hell on some (my) computers.

On my too.

1. For now, I will skip this. Many small particles make it very very laggy.
2. Make the hinges auto-brake and set lower the torque or use springs with high damping between the chain parts.
3. Select the object (patty, bun...) put on the right position, press ctrl+c. Create a laser, go to Script menu, OnHitByLaser=(e)=>{}. Click into {} press ctrl+v and enter after it. Set a laser activation key. So, when the activation key is clicked, a copy of the object appears.
