Yes I under stand that. But the only part of the Hierarchy that rotates with the variable pitch is ~CS_BladePivot. ~CS_BLADE is stationary and cannot rotate. The ~CS_BLADE object tells real flight that it and all of its children are part of the propeller blade and should be duplicated, ~CS_COLL ~CS_GLOW... Or in the way that I found that works for V-Pitch props is to name some object cube etc. ~CS_BLADE. Then name the visual blade ~CS_BladePivot.The ~CS_BLADE is the visible geometry as shown in this threads original post. The ~CS_PivotBlade is the "Dummy" object.
You either need to import it as the closest stock propeller. I really dont know how to create the physics for scratch i have tried and got mildly successful results. But there is no easy way to import the performance data and or pitch model you either need to make it from scratch in the .propeller file or import it as a close approximate.Hey, question: How do I import a new propeller's performance data or pitch model?
