More Awesome Than You!

Could someone tell me what thumbnail file I delete in order to refresh all my sims' pics on the UI in the game? Thanks

Those pictures are stored in the character file, not in tumbnails.
I'm not sure there is a way to refresh them en masse.

the lot debugger can refresh them

It can only refresh one thumbnail at a time. I think Braveheart wants every thumbnail to be refreshed.

There's nothing in the thumbnails folder that would apply to character thumbnails, I suspect it's just not possible to refresh them all at once.

Besides, the only reason to refresh thumbnails is because there are very few angles your sim looks good from.  Refreshing en-masse means the odds of everyone settling on a good one are vanishingly small.

If Braveheart wants to refresh specific NPC thumbnails, the best option probably involves the lot debugger and making them selectable.  Afraid I can't say with confidence what will happen if this is one of the oddball NPC's like PT, Crumplebottom, or the reaper.

Thanks for the advice people. I will try the lot debugger I suppose although I tend to be a little nervous about using that thing.

Goodness, why? The lot debugger is invaluable. Everytime I forget to have one on my lot, I discover I need it. And JM constantly updates it with new shiny useful stuff.

If you have the Clothing Tool, it also has a "Regenerate Portraiture" option, in case you do not want to use the FFS Debugger.

Being from the stoneage I simply make them 'change appearance' in the mirror to refresh their thumbnails when I want to - which is rarely. I don't change anything, necessarily, just go in to the screen and click the tick.

"Change Appearance" is a lot slower.

Change Appearance does not always regenerate the thumbnail for me.

Me neither.  It always regenerates a thumbnail if I actually change something, but if I've settled on the "perfect" appearance but the portrait stinks I'm just out of luck.  I finally decided to grab the lot debugger and it works (almost) every time.  (And I think the "almost" is simply a case of the game randomly rolling the same number twice in a row.)

Changing to a new set of default skin replacements is also a very good reason for wanting to do this.  My aliens look very different in real life from their image in the phone book.

Your aliens in real life... hmmm, freaky.

Could it have any influence on the portrait regeneration if there are actions queued up for the selected sims? Sometimes it seems to me that when the sim is talking to someone, it's more likely not to get a new thumbnail, if anything happens at all.
Oh, and doesn't the clothing tool also have a regenerate portrait function?
