Unreal PCG HDA node, how to output points? 2026年2月24日5:09
Hello,
I'm trying out the new PCG Houdini Digital asset node. I managed to generate meshes with my HDA on PCG points. As a next test I want to spawn a point cloud from my HDA into my PCG graph, but I haven't been able to figure out how.
In the documentation it says:
How do I use this attribute? I couldn't find this attribute in the Houdini Engine for Unreal list of attributes.

The HDA PCG node can create raw PCG data instead of Unreal objects. For example, an HDA may sample a Houdini heighfield and return a list of points rather than a whole landscape. You can use unreal_pcg_params to export parameters and attribute sets.

OSM & Mapbox fixes/alternatives 2026年2月24日4:51
Hello,
I've been working on this topic as well. There is a video from Entegma called "Houdini Game Tools Assembling a 3D Scan Of The Earth", going through another method for aligning osm with height.
Their way of downloading heightmaps didn't work for me so I ended up getting height data from QGIS and the plugin OpenTopology and other sources. I then used osmosis to clip the osm in the same region and the Entegma method of aligning it in houdini. I thought about writing a blog post to go though the steps as it's a bit complicated
Otherwise you might want to look into the "Mapbox on steroids" node that someone made, haven't tested it in a while so don't know if it has the same problems as the original.

Amazing, I was just looking for a way to control normal intensity and stumbled on this post, how do I add them to my project?
