Attributes hided while I open Hypershade

[ckidding]

Whenever I open the maya Hypershader window, the attributes on mnprMat will be hiden. Is that a bug or it is set on purpose? I find it wierd when it happens. Thanks!

This is due to the way Maya works, as only one window can show/modify the material attributes, i.e. either the attribute editor or the Hypershade. Once you open the Hypershade, you will only be able to modify the material attributes from there until you close it.
