Slope Meta Command

[Philippe Hurbain]

I too think the meta is the way to go. Could be useful too to define shinyness of a part, some of them are not shiny at all (I guess depending on plastic material), or only (similar to slopes) on a portion of the part. Examples of such parts: the Friends slide is shiny everywhere but on the inner of the ramp, the Technic flat panels are shiny inside ribs but not elsewhere.
