Problem summary
Nodes can be Shift+MMB dragged or copied and pasted into the Add Node box of an InteractiveRenderFilters node. However, when copying and pasting a chain of nodes, they are not pasted in the correct order.
Steps to reproduce
-
Create an InteractiveRenderFilters node and click the + to add a new filter.
-
Select a chain of connected nodes and press Ctrl+C to copy them to the clipboard.
-
Right-click into the Add Node box in the RenderFilter’s Parameters > Paste. Result: The nodes aren’t pasted in the same order they were originally connected in (In 2.0 and 2.1 Katana versions the nodes are pasted in reverse order, in 2.5 they are pasted in a seemingly random order).
Workaround
Copy and paste the relevant nodes into the node graph, then press Shift and middle mouse drag them into the Add Node box.
Reproduced by support
Katana 2.5v1, 2.5v45 Windows 7
Katana 1.6v3, 2.0v1, 2.0v5, 2.1v1, 2.1v5, 2.5v1, 2.5v5 RHEL 6.6
Expected behaviour
The nodes should be pasted in the same order that they are connected in in the node graph.
Actual behaviour
The nodes are pasted in a different order.
