"Dynamic Branch" node not working correctly

[John_Alcatraz]

There is this node in the material editor:

The tooltip says:

The code connected to the “Color Input 1” will be executed if the alpha is greater than 1 and the “Color Input 0” input code will be evaluated if the alpha is 0. Dynamic branches are best used when masking 20 or more instructions or a texture sample.

That makes sense to me, I understand that as “This node has some cost, but once you mask more than 20 instructions it’s worth it and will improve performance”.

But that node doesn’t work. No matter what alpha (I used the vertex normal for testing), the performance does not improve, it’s always doing the full calculation for the whole material. Is that a bug?

Currently this node does nothing. For dynamic branching use custom node. I’ve slightly touched the issue in this thread, so you are more than welcome to follow the issue tracker link there and vote on feature request.
