I'm trying to create a connector that I can toggle between RBE2/shell generation, and I can't figure out how to get either of them to realize properly.
Which connector setting controls the RBE2 attachment on the outer edge/surface? I'm trying to create RBE2 elements as shown in dotted orange, but the red RBE2's are what I'm getting with the settings shown below. Note that I want to avoid creating RBE2's in the green arrow directions shown:

Since both components have material and property assigned, I don't know what to try next:

Here are the LTB connector settings:
