Is there or will there be a way to import a WorldCreator heightmap? I can import an obj file but it leaves something to be desired. In WC, heightmaps are obtained from www.terrain.party.com which allows the choice of the area size imported. It also enables pretty accurate elevation scaling.
Thanks

in Houdini 17, create a Heightfield node.
Go inside, you'll find a heighfield node, you can delete it.
Create a new node “heightfield File”, in its properties select the file, tif, png … the grey scale image you exported from World Creator.
Most likely you will see nothing happens in the viewport, it seems flat. Now INCREASE THE HEIGHT SCALE until the terrain shows up, set the height to what you want. Try 100, 300, whatever works for you compare to the one you got out from World Creator.
Be careful with terrain.party it has very limited small resolution.
If you're interested in real terrains, I came across this, it shows high resolution maps and techniques to deal with them:
