As long as I stay away from the "water" parts the sets work fine, I can't seem to get the hang of the water terrains but that could be me. 23+ years as a merchant mariner can cause a certain aversion against the liquid element :) I use the light presets also outside the sets and to be honest I mix 'n match just about any part with anything with variable results. Imho there's a lot in these sets but they want some experimentation to get predictable results. I wouldn't advice the sets to people who'se sole interest is in the dressing&undressing of Vicky & co.
