Result:Thank you, its working, i didn't have the perfect texture thoughGlad to hear!
Hello welcome!Thank you, its working, i didn't have the perfect texture thoughHello friends. How to display 2D Image to the camera?I'd recommend the blitting functions of the FrameBuffer:
I'am trying to make a Joystick
