I have managed to implement wingflex to one of my projects, and the wings bend just as they should, which is great!
What is not so great however is that with the current way I have animated the flight surfaces located on the wings, every surface moves whenever I move just one of them, say for example when I move the ailerons the flaps moves as well, not exactly what it should do...
I have tried many things out, but none have seemed to work for me. I have taken looks at other planes with wingflex, and I have currently been parenting the flight surface meshes to bones that are connected to the right wingflex bone, then animated them as they should be, but it seems like when I get multiple nla tracks under the same armature object, every animation effects each other.
If someone knows a solution I would be happy to hear!
