Intuitively, neither topology refiner nor topology itself depends on the number of vertex-varying data, and one would think that it should be possible to modify the amount of vertex-varying data after topology has been refined. What am i missing here? sergey: I am not convinced this belongs here. Intuitively, neither topology refiner nor topology…
