Okay, so you're in your callback func and you want to set the value of
MYATTR on a node of type testNode?
Assuming that 'node' contains the MObject of the node and the testNode
class definition is visible to the callback func, you'd do it this
way:
plug = om.MPlug(node, testNode.MYATTR)
plug.setFloat(5.3)
If the testNode class definition is not visible to the callback func
then you'd do it this way:
nodeFn = om.MFnDependencyNode(node)
plug = nodeFn.findPlug("myAttr")
plug.setFloat(5.3)
