You need the template for the figuers eyelashes that your going to put lashes on. If it's V3 you can download the template at Daz. Then you draw inside the area that is meant for the lashes. You can start by making a layer and draw the lashes in a color you can see, eg red. When your done, change the whole template background to black, make the lashes white and load them as trans map in poser.
