Hello, Here's some TerrainToolbox feedback. I have tried importing my partial terrain tileset through terrain toolbox batch import and I'm getting errors. I presume that partial tilesets are not supported. Errors are either TerrainToolbox: Heightmap resolution per tile is not integer with current settings. You will get seams between tiles or TerrainToolbox: Heightmap resolution per tile is not square size with current settings. depending on the settings I've tried. Here is my tileset config. PS the reason I'm using partial tileset is because I don't need the terrain that is underwater so I haven't built it. PPS also, as you can see, my tileset doesn't start at 0,0. You might want to support that case as well, it would be a nice option to have. Thank you for your hard work WorldBuilding Team.
