[rancoud]

Description

Control rig blueprint are not render correctly.

Steps to reproduce this issue

1. Create a control rig blueprint
2. Copy paste

Expected behavior

Have nodes, pins and position showing correctly.

Actual behavior

All nodes have no pins and no body, title are incorrect and position are 0,0.

Additional context

Someone at Epic Games decide to use another way to generate blueprint code.
For example the position of a node is using 2 properties with integer values NodePosX=-4208 and NodePosY=1728 but in case of control rig they use 1 property with float value Position=(X=-6527.000000,Y=-1739.000000).
First Begin Object are the nodes at the begining using hiearchical pin declaration.
Then at the end Begin Object are the links. They are now an external object at the end of twith a source and a target instead og being a property of the current node.
