@ellemat2, As long as we are talking the Textures Adjustment in Studio, yes sure you can mirror or tile textures.
BUT... That option only show up under conditions.
When you apply click on an individual Texture, it is by default added across the image. You cannot see any options to Mirror/Tile/Extend.
BUT. Thats because the Texture default fills the whole image (cannot be tiled).. Click the "Edit" button, and resize the texture area, using the sizing bars that appear, to be a different (smaller) size, and "magically" an "Edge Extension" selection show up in the Adjustment selections (right between the existing "Lock Aspect Ratio" and "Texture Location").
Edge Extension allows for selecting to Mirror, Tile, or Extend the texture image across the image being edited.
Now.. Given the "Edge Extension" name the option has, I should say that I cannot be sure whether that option shows up in my Studio 1.5.3 only because it was added to Textures as part of one of the other paid "Edge" type Adjustments.
Don't think so, but that COULD be..
