What files do you put download animations and characters into if you have the all in one pack?
From your main folder (that contains the game applications), follow these paths:
For mods (in .zipmod format)
Main Folder > Mods > MyMods
*note that you can drop a mod anywhere so long as it is in the 'mods' folder, but by putting it in 'MyMods' if it is a mod not
already included in the modpack, it will help you stay organized.
For character cards (in .png format)
Main Folder > UserData > chara > female (or male, if you've downloaded a male card)
For outfit cards (in .png format)
Main Folder > UserData > coordinate > female (or male, again, if it's an outfit for a male character)
For Studio scenes (in .png format)
Main Folder > UserData > Studio > scene
You shouldn't need to make any new folders, they should already be included if you've correctly downloaded the full modpack. If you would like to further organize your work, you can make folders within the locations given above, that won't mess with the program's pathing.
