I am creating blank images within blender to add some fine detail, such as nails in wood boards. My blank image is black.
When I export the image and/or when I input it into image texture node in cycles, I cannot control the alpha channel, as it hasn't been saved.
When generating a new image, I am using all the default settings (including the option to create an alpha channel). Any suggestions on how to generate an image with usable alpha channel?
