After effects nulls have no track data?

Hi there-
Trying to learn a bit about Mocha Pro during my 14 day trial. I create a mesh using power mesh, and when I save the project and the track and go back into AE, I click “Generate Nulls” under the powermesh tab in the Effects tab.

the nulls are generated but none of them have any motion with their position?

Any advice?

Since you’re new to this, did you track the mesh?

What are the final effect you’re trying to achieve? I can recommend you checking out the section dedicated to Power Mesh from free Mocha Essentials course. This will give you a great understanding how this tool works
