Hello @Pravin_Poudel
As we saw in your previous topic, there is no need to explicitely give the offset field anymore in TTK. Providing a non-conforming array may indeed lead to error as the order of the vertices may not be strict anymore.
You may also use the ttk-data repository. With the latest paraview and the provided TTK, I was able to load the dragon.pvsm state, which has been updated (contrary to the video).
In this new version, there is no offset anymore:
Best,
Charles
