I am getting upset with myself for asking but I really want to know lol


What is the name of the Pyjamas in imgtool? (I found SP_PJ_L.nif and SP_PJ_T.nif but I think u need 4 files to delete right? (I only found 2 nifs and NFTS and u need to delete 4 files)

Whats the name of the BMX CHAMPION in imgtool? I can't seem to find it :/
