Generate Landscape data based PCG with a blueprint

Hi everyone,

I am facing a problem with PCG.

I have a blueprint with a PCG component set to Generate on demand. I have a basic blueprint setup that cleans everything then generate the PCG.

When I base my pcg on spline data and put a closed spline in my blueprint, everything works fine but when I sample landscape data, nothing is visible and there’s no error. Is it impossible to generate landscape based PCG through a blueprint?

Below is my basic blueprint setup :

Thank you very much for your help.
