But the name is misleading, so is the name proposed in t3 list, other
shaders have the proper name with the proper controls, so I do not see
why not name it Minnaert and put a B toggle, or put Minnaert and
MinnaertB. This way avoids problem when people really need to know
what is behind (like addapting materials from other apps, or using as
simulation tool). People that do not need to know about the detail
should not have problems: yet another shader named after someone, just
"play with the control until it looks as desired".
