Clothes simulation is not active in skeleton mesh view

Hi there, Can I get some advice what might cause this issue?

This was my quick workflow

  • create a simple plan with good amount res from Maya, and export it as fbx (no joint)
  • Import fbx as skelMesh
  • In skeleton mesh view, right click the mesh, create clothing data from section
  • After clothing data creation, go to activate cloth paint, and pain the area that I want to simulate
  • Deactivate cloth paint
  • Right click the mesh, apply clothing data and select clothing data I just created.

I’ve watched other tutorial videos, and it works after these steps while mine is not.
I checked “character → cloth → Enable cloth simulation” is checked.

Would you please share some insight what might stop it from getting simulated?

Thank you so much in advance!
