HOW TO CHANGE SKINS BODY/WHEEL:

PLEASE NOTE: The skins file name must be renamed to body_skin otherwise it won't work.

Once you have found the skin you would like open futo.ytd, find body_skin you are changing, in the list and then delete the old skin. Once that is complete you MUST click import and the choose your selected skin.
When you have imported the skin for the body skin you need to select properties > MipMap Levels > 1.

PLEASE NOTE: It's ideal that you also put the skin file into futo+hi.ytd with the same settings
