I know you can use design images to “trace”, as in map images to the boxes… but is there a way to import directly into shadowbox as a mesh?
I’m not aware of a way, but you can convert any grayscale image into a mesh using the “Make 3D” feature in the Alpha palette.
You can use a black and white image to create the alpha mask:
