If you have a bunch of layers in the landscape layer blend node and you start altering them having height blending, deleting layers, adding new layers etc, the network gets screwed up instead of staying connected to the respective node sections is should be with.
This is what I have to start with
And this is what happens when I change Test1 to have a height blend. It just added it and kept the nodes connected to the same order, but not the right slots.
This is what I think it should do instead. It should keep whatever lines are connected to whatever notes and open up a new node in the right spot. This is the current functionality of UE3… so i imagine this is just a bug.
Hope that was clear enough and hope this gets fixed soon enough! <3
