cgmAttr


Description:
This is our attribute MetaClass using the same principles as we learned from red9 for maya nodes. Why would this be necessary when we have other metaClasses for adding and editing attributes? Well, this kind of object can follow an attribute as it is swapped between objects and many other features. It is also useful for attribute specific work because of it’s formatting options and how maya is variable in how it needs info – sometimes node,attr, sometimes a combined string.
