I don’t think this is available and realized it would be very useful for me.
Would it be possible to implement a feature that lets you paint Height on landscape and mask it by a certain landscape layer?
Lets say I paint out some larger gravel, then i use this feature to only raise this part of the ground so that the gravel pops out a bit more. Or have sand between patches of grass a bit lower to simulate it eroding where there aren’t any roots to hold it together. Sure it could be done using the heightmap we import and matching it to splat maps, but tiny details such as these would be so much easier to do in the engine.
