Sculpting and keeping an image visible 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.

Thanks!

Instead of using background images you can use an empty to place an image in the 3DView.



You then get a reference image that is always visible as you rotate around.
