Once again I was having a conversation with Amaz2k12 and I ended up thinking, "Hey, I should make a video about that!"
So I did. :P
This time I am talking about the L.I.E. image editor in Daz Studio. I mostly use it for Blushes, but I do have some eyeliner, makeup, and lip options that use L.I.E. as well.
However, if you really know how L.I.E. works, then you don't really need it. You can load the same textures into a 2D editing program and work with them yourself. In fact, it's generally more efficient to do things that way.
There is an image set for Stacked patrons attached, and a video in the Bulging Bazooms Archive.
