I’m working on making terrain that is editable and buildable. I would like the player to be able to make a cave into the side of a mountain using some kind of blueprint for the cave opening then an editable mesh for the cave itself. I know that the feature exists to make a hole in terrain using materials from the editor but I have not found anything so do this from in game. I would like to stay away from using voxels for the terrain and just use a height map terrain with the caves.
afaik this isn’t supported via blueprints, but Ali Akbar is working on a plugin similar to what you’ve described.
You can’t add caves using heightmaps, unless you make it multidimentional or use some kind of mix between cave models and “suppression map” (A map where you make holes in the ground), but frankly, use voxels for when you make the map, then you can bake the voxel so you end up just with a map.
Thank you for your input. For now i think im going to stick with a static terrain till i get more or the game mechanics done. I might just take that feature away and have the player just work with what i give them.
