I am trying to export a drawing file as a .psd, but every time I open the newly created file in Photoshop, the background is always pure white. I've tried changing both the background color and the color of the paper, but it the background is always pure white. The "Remove background" checkbox is not checked (it isn't even an option) when I save the drawing as a .psd file. The image type is set to "RGB full color" when I save.
Thank you for any help you can provide.
