But after that I have some troubles and made a new question. I tried to create an high resolution image to use as wallpaper, and I used the print screen button in my keyboard, but this made a poor resolution image. Then moonbots tell me to go to camera mode by pressing 0 on the number pad and press F12 to render, and I did that.
The image is much cleaner than print screen button, but another problems appears:
1: the character isn't 100% focused: some few parts have blur.
2: the blue background does not appear, in rendering the background is all black
How can I adjust the camera focus and how show the blue background in render or put an picture instead of full black background?
the background color is black and the character isn't 100% focused
P.S. sorry for asking so many questions
here, how disable depth of field? and the Transparent option is disabled but the background still black
