In this example renderLayerNode is inside of foo's scope so you can
not use that variable outside of it unless it is a global. I dont use
pymel, I use Maya Python and it would look like this:
def foo():
global renderLayerNode
global scpt
renderLayerNode = "foo"
re
Every thing is inside a function.
def foo:
renderLayerNode = PyNode( "deaultRenderLayer" )
scpt = node.myScript.get()
Suppose script on string attribute on node is:
print renderLayerNode.name()
val = renderLayerNode.myAttrib.get()
Using this:
exec( scpt, globals() )
I get en error:
#
Can you give a more clear example of what you are wanting to do? You
say external are you trying to print attributes from other modules? If
so you need to import those modules and prefix the attributes with
that modules name.
# This works
a = 1
b = 2
scpt = 'print a, b'
exec( scpt, globals() )
#
