I am attempting to perform linear interpolation using the spline factor, transitioning from yellow altitude to green altitude. However, when I try to capture the factor attribute, I consistently receive a value of 0 for my mix factor. Can anyone provide guidance on how to successfully achieve this interpolation? Your assistance is greatly appreciated. Thanks in advance.
