Hi,

I am trying to create an HDA about automatically generating roads according to an OSM file. Now I have created a new asset in Python as a geometry to load an OSM file. And the output is some primitives consisting of many points. The subsequent part is to generate roads with the outputted primitives. Now the subsequent part is done. And I want to change the points' position from the first asset in UE4. I add the asset as an editable node. But it doesn't work. How can I realize it?

Thanks,
Terry

Hi Terry,

I'm not exactly sure I understand what you're trying to do:
so, your asset is loading an OSM file, processing it to prims/points and creating roads geometry from it and you want to be able to change the source OSM file?

If that's what you're trying to do, you don't need an editable node for that but just a file parameter:
just expose a new file parameter on your HDA, and have your python script use that parameter for the OSM loading.
