I can add a background image and, for example, assign it to top or bottom, cut off half the box, mirror add my other modifiers but this is when the problems start.
If I try to sculpt, the image simply goes away. I have to hit top and then orthographic again to get the image back.
I guess I could assign the image to the camera and do the same thing and it would stay there, right but why does the image go poof as soon as I grab a brush and try to do anything to surface I am going to start working with?
If anyone knows a tutorial that covers this, please let me know. I have chased my own tail for 4 hours in YouTube and in the Blender.org community and not found an answer.
