Getting Attribute values from MFnNumericAttribute?

[Anonymous]

I am walking through a list of connected nodes, from selected object to assigned CGFX shader and want to get to the stored values of the attributes inside the shader. I can get the attribute list but can't their values. Anyone know how?

I've been looking at trying to access the attribute values through MAttributeSpec as well. Still no luck.

Never mind... I figured it out.

I realized that the MFn...Attribute classes were meant more for assigning and creating attributes than for querying them. After a little research I found that I wanted to use the MPlug class, and now it works great.
