Thanks for the link Henry, you did a huge and fantastic job with that book!!!
But my current problem is how to make, in v16, an image with transparent background (like a photo of a tree or a 2D human silhouette) to be used in a 3D model showing an exhibition.
In former "Treemask" the image background which should be transparent must be black, I guess this is the same when using "Wrapped image"?
