Can you send me the mesh by pm, email or link it here? I would love to have a look.
I can’t tell you exactly how you can import it into your project as I don’t know your project. In the demo, the mesh import consists of an actor in which the procedural mesh component is created. The file is read out in the UI and the PMC is then fed with this data. You could perhaps migrate the actor into your project and copy paste the rest.
