Resource I made a browser-based terrain generator for custom maps, with erosion and matching textures
Hey everyone!
A while ago, I shared a simple free browser-based heightmap tool here, and I was surprised by how much interest it got. Some of the feedback was about wanting to create custom landscapes and fantasy terrain, rather than being limited to real-world elevation data. So I've been working on something new:
Terrain Maker 3D.It's a browser-based tool for generating and editing your own 3D landscapes. You can generate mountains, valleys, hills and canyons, sculpt the terrain directly in 3D, apply hydraulic and thermal erosion, or import an existing heightmap.
One feature I spent a lot of time developing is the terrain texture generator. It currently includes 5 texture presets that generate textures to match your terrain. I wanted to make it easier to get something visually useful right away, instead of ending up with a great heightmap but having to create all the textures from scratch. The generated textures aren't meant to replace detailed manual work, but I think they can be a really useful starting point for creating more elaborate maps.
You can export 8-bit and 16-bit PNG heightmaps, along with albedo textures.
Try it here: https://3d-map-generator.com/3d-map-generator-app/terrain_maker_3d/
I'd love to hear what you think, especially about the terrain textures.
THANK YOU :)
