I created a terrain through Houdini and imported the hda file into UE4.
It works well but if I want to get roads information which is including height/width from UE4. I have to re-export the heightmap from UE4 into Houdini and re-create a terrain and rematch the height.
So how to iterate the heightmap between Houdini and UE4 if I want to get some roads info or any changes in terrain's height?
Thanks in advance.
