    • A message may appear when selecting the picture to allow its compression.
    • You can create several hybrid features. If two mapping zones overlap, a message appears and the zones are displayed with different colors. Cut the subdivision surface in the middle to have two separate zones.
    • If a picture is mapped onto a closed surface, the detail may be truncated or twisted.
