Hello , i started houdini a few days ago , i am interested on dynamics and visual effect and i am trying to test somethings , i modelled a chain and gave them rgb object , i modelled some sticks and gave them static obj. When i press play , chains started to fall down as i wished , but in this point i want to learn two more thing :

1- how to interact chains and sticks naturally ? because my chains in some frames inside of stick



2- how to make chains to slip on stick to down , i mean how can i create friction between chain and stick





thank you for your answers , i am happy to join houdini family
