Softimage ICE relative referencing - how to do?

[Petr Zloty]

Hi,

Is it possible to get relative object name referencing in ICE tree outside
the Model scope (name space)?

e.g. I have this structure:
Scene_Root
  |---Model_A
          |---Null_a
                |---Model_B
                    |---Null_b
                          |---Pointcloud_with_ICE_Tree

I know I can reference "Pointcloud_with_ICE_Tree" with Get Data "self" or
"this"
I can get Null_b with "this_parent" or Model_B with "this_model".

But how can I get relative reference to the Model_A? Or how can I get
parent of the Model_B without absolute path (name of the Model_A could be
change (e.g. by duplicating rigs))
