I download some dwarf parts that are made to make my own look for dwarfs in the mine. which i thought is cool. however, i watched a video about how to put them into the file. is the video i watched. it says that all the files need to be named something like this FG_Clothing1_p25_c1, FG_FrontHair_p01_c1_m003, etc. well these dwarf images i got are not in said format. there is 185 pictures and they are all just ears_01, Beard_01, etc etc. do i have to change all the names like FG_Beard_p01_c1_m003 but change the po1 to p60 or some number different. i also have question about pre made sprite assets. i see a few on itch.io but if i buy those do i just have to post them into the file needed or will i have to change abunch of names like i do in generator. also if they are made for mv will they work for mz. https://everlywritesgames.itch.io/nine-realms-nidavellir-dwarves-pack is what i was look at. please and thank you. you guys are very helpful to newbs. ive posted a good bit in the last few weeks and i am sorry lol
