   cegui static image window problem
  Hi guys, I am making a game with my friends now, and my artists give me some irregular textures for our game panel texture. i put them into a CEGUI staticimage window, and set the image property to the irregular texture,but the problem is the other part of the window is not transparent so the other part of the window is black. if i set the window alpha property the image will also be affected. So is it possible that to solve the problem using CEGUI or i have to switch to Navi or other GUI library? And if i switch to Navi, can i implement split screen with two scene managers like using CEGUI?
