Hi!
1- I create a HDA inside Houdini. The only thing that it does is to receive a Landscape input and add noise to it. Thats it.

2- Once in Unreal, I create a new scene and add a landscape to it. Just a simple landscape and hit the Create button. No editing, no nothing, as simple as it gets.

3- I then import and drop the HDA into the scene, assign the landscape to the HDA.

4 - HDA creates a new landscape with the result. The scene ends up having 2 landscapes, the original and the result of the HDA.

Thanks!

Try checking the Update Landscape Data box

Yes, you should enable the Update Input Landscape Data checkbox on the input.

As long as you do not change the actual resolution of the landscape/HF, the plugin will modify the source Landscape instead of creating a new one.

I am wondering if “Update Input Landscape Data” checkbox would work with landscape streaming proxy.

I am using world composition in UE4 and I end up having 2 landscapes when I use landscape streaming proxy as a target landscape input.
