The snow and sand need to be placed 0,1 off the ground and from eachother (as there are several used) for not to flicker as they do currently.
Town hall lobby
Forgot that you can't set altitude in NWN1 by number, not so sure how to fix that flickering if snow drifts are top of eachother. :)
You can, actually, but snow drifts? This is new to me. >_>
Or fake snow drifts, or whatever they are emant to be. I guess some civil servant did some brainstorming and thought it would look good to have an exotic part, an arctic part etc. of the lobby.
I'm guessing some DM put these down for something he was running, and I imagine they'll be gone by the next reset, otherwise I have no clue why there's snow and sand in the Town Hall.
Nevermind, I was wrong! The novelty lobby decorations should be adjusted to not flicker.
