well, i'm still struggling with figuring out node usage, and building my own shader trees.  i was telling someone the other day that i want, at some point, to be able to walk through say a supermarket, or a Wally World since they've a large mix of stuff, and in my head as i look at things, i'm building shader trees automatically.  i believe that i can do this, actually, to think in what i've dubbed for myself 'node language', i just need to get certain verbiage down, figuratively speaking, as i excel at conjugation.  [silly grin]
