I'm trying to realize 3D renderer (stereoscopic) in an application. It's working on Plane GameObject but I would like to do it on GUITexture. Is it possible? Because when I'm replacing my plane by a GUITexture I have some sort of alpha problem ...
Could you please add some detail as to what you are doing. And be more specific than "I have some sort of alpha problem." You don't need 3D rendering software when making GUI textures as they are 2D. Use 2D painting software like photoshop to make a picture then add a GUI script to say...your camera. As for your alpha problem just delete the area of a picture you don't want to show then export it as a .png which keeps transparency
