More entities per page than just 200.

In my opinion that's the single biggest issue with sketches.
Every map I've made it felt more like making a puzzle than making a drawing, from trying to stay just below that limit.

Funny, that tavern has been on my mind a lot lately... and I can't say I'm surprised to see this thread.

I rather like the idea of a tavern run just by players. Much as I like Allelia, I wouldn't particularly care for sharing the bar with her at Kada-El's. Although, considering the Broken Head's layout, I think an NPC there might be less of a problem.

While have tended the bar at the Broken Head a little, I hadn't decided if I should put any real time into it. But with this thread here, maybe there'll be more than a person every two hours.

( Also; it'd be nice to have a kettle there. )

That probably isn't enough. They were made impervious because they became exploitable after getting stuck, and that continued even after an npc died and respawned.

Okay, actually the worst thing is there is no map! zip! nada!

the creator pretty much flatly refuses! "There will be no maps, because they ruin roleplaying!  Exploring is fun!"

It seems to me that this gets repeated quite a bit, but really, there are maps.
I'll admit there's not too many, they're not always helpful, they can be hard to find and the sketching system can use some more improvements. It's being worked on.
But using the tools available in-game right now, it is possible to create a good, detailed and accurate map. If you can't find one, make one.

That's the default settings. Since you're using windows, your personal settings should be in %appdata%\PlaneShift\Options

It isn't nearly the same thing, -relight recalculates the lighting of a map when it is loaded. It can take a few hours...

I have seen the same thing happen a few times, at load-zones and after I was sitting for a while, stood up and took a single step. All stamina drained away very rapidly. If it was simply lag, it should drain at walking rate for a while longer than normal. Unfortunately has only happened a few times over a rather long period, and I don't know of any way to reproduce it.

Unfortunatly, I'm not good at drawing... the way I make these is closer to vectorizing existing images. Mainly screenshots, so far.
Unless you were looking to get your existing material as in-game sketches, I'm afraid I wouldn't be much help.
