My Blender duplicates the render I'm new in Blender. I have a problem. When I hit F12 to render my project with Cycles Render, the Blender duplicates the image. I think it will increases my render time.



So I just don't want this happen. Anyone can help? Thanks for the reply
To disable tiled render display, use N button in Render window to show properties panel, then in Display section disable Repeat. If the image is offscreen use F button to center it.
