I have a couple old skins for the V3 model is there a way to snatch an image of the Mat? I would like to use these again but first I would like to alter them to suit a a new purpose. Is there a way to get a jpeg copy of the surface of V3?

More than likely it is already a jpeg (could be png or bump)

Just open it with your 2D editor of choice and do desired alteration.

Specifically there is a file already on your computer with the texture. In Daz Studio it's referred to as the Diffuse Map, other programs call it a Texture Map.

On Windows it's under your Runtime/Textures folder, but there's usually a lot of stuff in there.  Also, most models have several textures for one body, ie. one file for the face, one for the torso, on for the arms/legs.

  If you know who made the texture you can sometimes search your Runtime folder and find it, otherwise try this:

Load Vicky3 and apply the texture.

Select Vicky 3 and open the Surfaces Tab of Daz Studio (Main Menu ->Window -> Panes (Tabs) -> Surfaces).

Make sure the Editor tab is selected near the top of the pane (not the Presets or Shader Baker).  There will be a listing of the various body parts.  Click on the Torso (or closest equivalent, maybe SkinBody or something).

The file you're looking for is under Diffuse Color.  There will be a color selector and a small box with a down arrow.  Click on it and select Browse from the top of the list.  This will open a dialog box letting you select another texture map.  While you don't actually want to change anything, this will let you know exactly where the files are located.  I usually go up one folder level in the open dialog and then right click and click Open In New Window, to get a new browser window.

I hope this has been more helpful than confusing.  All info is based on Daz 4.6 and Windows.  Your milage may vary.
