I do a lot of texturing for presentations in woodgrain and steel, and it would be really handy to have a simple GUI option like the gumball for rotating textures on surfaces. Box mapping is great, but having to make a different box for each surface when there are 20 or 30 with various directionality is really time consuming.
Gumball works on mapping widgets - is that what you mean? You can turn on the mapping widget for the box mapping of an object and monkey with it using Gumball or other transforms.
This is great, exactly what i was looking for, thanks.
