The Model attachment feature with their own xml files seem like it would be perfect for adding tablets, displays, instruments and switches to both default planes and our own aircraft.
Unfortunately it seems like objects/nodes in modelattachments can not be clicked on / pushed / interacted with, neither with the code in the main xml nor in the attached xml. Adding a panel material (to show a gps screen for example) also does not work. The panel material does not activate. These objects seem to be passive and can only receive variables for visibility or animation.
Is this intentional, is it a bug, is it me failing to use it correctly or is it just not implemented yet?
