1. What u mean by stances explain pls.
2. Editing maplist.csv , check out korean one it has new maps for loading of chars 100-106, also be aware that u need to edit (dont copy korean values they are will not work), camera_height, camera angle ...etc on that. then u need to copy files in map folder and maprdcell, that's server side.
Client side same for share folder + add textures (hope u know what i mean mesh,texture,skel.. etc.. ) + edit modeleffect.csv + soundscript.csv + property/effect edit efectscenes that are required for chars loading u will see which they are + also dont forget to copy map files from /map and light_*.txt i think i told u almost everything u need to make it work p.s u will need about 1day to make it work expecaly u will have little problems with camera but dont give up just figure out what u need to edit (also u might not be able to see char thats because camera position is at wrong place but just change values in maplist.csv and it will work. did this long time ago , 8 good months passed but still remember )
Hope i helped u little :P
