Accessing generator's input spline in script, changing it at runtime

[smackledorf]

Hello. I've gone thoroughly through the documentation, api reference, YouTube tutorials and searched here on the forums, but cannot find anything that can explain how I might reference a geneator's input spline path module and assign a spline that was created at runtime. I already have the spline created and configured at runtime and I have a reference to the generator in question, but I can't understand the method or module reference syntax etc. If someone could help it would be very appreciated. Thanks
