Now it's me who doesn't understand!
Lately I've just been leaving a small fraction of surface to unite any shapes that are sliced within a rectangle. This has been my improvised solution in order to no loose a texture position.
Below, a picture is better than a hundred words.
I don't understand your example, is it this?
- Make a plane rectangle shape R and fill both faces with a given material X, position the texture as desired with the unfix yellow pins.
- Make two separated rectangle shapes within this R rectangle, paint them with any material other than material X.
- Right click on one of the faces of these rectangles, select position and then done.
- Move the faces? Like switching faces, or Frontface to Backface, or what?
Please post a picture, and hello to Hungary,
