From rad to hbjson file or directly change hbjson file?

Hi the community,

I have a question about running annual daylight simulation for sDA independent of grasshopper. I already ran the simulation once and got the models(.rad), grids(.pt), sky mtx… Right now I’d like to change the material modifers and rerun the simulation again. What might be the easiest way to handle this?

My thought was changing modifers in .rad files but I did not know I can transfer rad file to hbjson format. Or directly change the .hbjson file and use ‘queenbee local run …’ command?

Many thanks for your comments in advance!
