Pretty much the tittle, I am referring in object level, how to turn on/off lighting on objects and the same function on casted shadows. Redshift has this feature, but can’t find it in karma xpu. Thank you

I`m not entirely sure what you mean but i think what you are looking for is a node called

lightlinker
you can use it to link lights. it is howeverin the lops context as you generally want to use the lops context when working with solaris. ( you can just do a scene import if you dont want to setup evrything.I`m not sure what you mean.

I think you can just do
suboutput.setParms({
"name1" : "albedo",
"label1": "albedo",
"name2" : "rough",
})
