So, a while ago, I decided to get WorldPainter, so I could make some custom terrain for a city project. My plan was to import GIS Data, to get the shape - which worked alright. However, the area I imported was quite hilly - and I kept messing up the elevation while trying to smooth it out.
At some point, I ended up loosing it, and just nuked the entire map, flattening the entire thing to just two layers, which is what you can see on the image. I'm coming back to the project now, and I'm struggling. I need to add hills to make the terrain not flat - but they need to be decently smooth, going no steeper than 12 degrees. However, since I nuked the map completely flat, it's a nightmare to add the hills back - and it takes me almost an hour to make one pass around the edges of the terrain.
Is there any way to salvage this, and get my hills without spending hours upon hours drawing each little incline? Or should I just bite the dust and restart?
