@me1958424 Oh, 2.79 wasn’t even an option for per object.. either everything is or nothing is.
That said, if you look on the materials properties, there is an option to have each material show a different color… Viewport color. In the solid shaded mode, it will use this color to shade your object. Not quite the matcap you were looking for, and it’s per material, rather than object, but perhaps that can help.
