Yes, you heard me TEXTURED JOINTS, somehow I don't know if you know how to do it, i don't know, because I didn't find any textured joints topic ok... go to your custom folder select your player you wanna edit now, just copy one TGA. file (if there isn't one in your player's folder then just copy from another one) now i can't seem to crack the templates, so just draw randomly just paste the file open it, edit it, now rename it to

Example :

Textured Left Ankle : j_l_ankle.tga
Textured Neck : j_neck.tga
Textured blood : NON i said joints not blood duh

yep now you can have all your textured joints you can have

This is in the Ultimate guide to unleashing the true potential of your custom folder.
;-)

And im pretty sure the template is same as head =)
