One thing I have noticed, at first I used to also select the update and cancel in the palette selection portion and whenever it would try to select a shade of red it would cancel out of the painting and spin in circles as if it was still trying to paint. Another thing on sketches and things of that nature (like my profile picture on here) if actually can't draw stuff like that. It just makes a super shaded picture and tries to go deep into detail with it. Only two things I've noticed so far.
Hello Patrickk, you are not to include the Update/Cancel buttons in the Controls Area capture. Please refer to the tutorial or demo video for a more detailed explanation on this. Also, try using the Grayscale image tool before painting your sketch. After you load the image, right click and choose Image Tools -> Grayscale.
