Hello,

I'm testing the PCG HDA-node with a simple setup, using landscape as an input. I don't get any points out from my HDA though.

This is my setup:
- PCG Graph with Get landscape data
- HDA that takes the landscape as an input, scatter points and outputs the points with i@unreal_pcg_param=1

Is this supposed to work and should I do something differently?

The "PCG Landscape Data" returned by "Get Landscape Data" isn't currently supported by the PCG HDA node. So I don't think anything is being passed to the HDA, hence no points are sampled.

However, you can pass a Landscape Actor to the input, which you could do via a PCG Parameter or by configuring a "Get Actor Data" PCG node to return the first Landscape actor it finds in the level.

If directly supporting PCG Landscape Data would be useful for you, please submit an RFE to the dev team, though I think all the data you need will be in the actor anyway.
