Your pack looks gorgeous down in the earth where everything can be smoothed and lovely, but I seem to have a bone to pick with most large-res packs like this in regards to surface stuff, where grass/trees/etc collide with the solid backgrounds of units or other tiles in a really unsettling way. Is there a way past this, design wise, in your experience? Your unit sprites are gorgeous, I just wish the surface tiles meshed more happily.
Mifki was working on creature transparency, but currently nothing is possible besides using a dark-grey neutral background.
Oh and one bigger issue... after putting an artifact on a display case, the display case now looks like a slightly darker normal floor and the artifact is invisible.
Oh, I didn't know that they change their look when something is in them. If you have one of those in the save, please point it out to me. Might be a TWBT issue, when a transparent item is on top of an override tile.
The hauling I can't fix. Item carried use their original tile.
Corpses I'd be happy to have a look at. They are hard to come by, when I start my little test forts, since I cant spawn them with dfhack.
Wagon... damn. That's good to know, but also quite bad. The embark wagon counts as building, so the override works. Visiting wagons count as creatures, no override possible. :/ They dont even use creature sprites, nor a creature tile... it's hardcoded to tile:178. Silly, it's used for smoke, miasma, dust, ocean foam, swarms of insects, fallen leaves and the wagon...
