You can actually drive all parms automatically on a node with the dictionary generated from attribfromparms
No python needed
1 Create a detail dict using attribfromparms called `parms` with parameter values. (Name is important) 2 Create a spare input on the node which you want to drive the parms for. Set it’s value to be the node you have your parms dict attribute on. 3 Create an integer parm called `spare_parminputindex` and set it to -1 (to point at the spare input connection)
Profit!
