If you were trying to test your textures without previewing them, you should do it in a separate folder like Voxus said because your custom folder gets updated every time you run the game. Name all your textures as follows
head.tga
breast.tga
chest
r_pecs
l_pecs
stomach
groin
r_biceps
l_biceps
r_triceps
l_triceps
l_hand
r_hand
r_thigh
l_thigh
r_leg
l_leg
save them to the custom folder you made, ex. TEST as in the previous post.
type /lp 0 TEST
this will load it to tori
or type /lp 1 TEST
this will load it as uke
Notice that if you create them on gimp or photoshop do not select the rle compression box.
If you dont have photoshop don use paint then convert to tga. Just make them in paint if you want, then open them with gimp and then save as .tga.
Hope this helps.
